Question: Calendar Not Syncing

My Apple Watch is not updating with changes to my calendar. It has had a few hours to update, but still shows the old time for meetings I have scheduled today. I've restarted my watch and my iPhone 6+. Is anyone else experiencing this? Is there a way to force a re-sync of calendar data between my iPhone and watch?


Thanks!

Apple Watch, iOS 8.3

I struggled with this as well and eventually removed all the calendars from my phone but everything was still on the watch. I was about to reset to factory but I found an option that does exactly what we want. In the Apple Watch app, go to General -> Reset -> Reset Sync Data. The text underneath says it all: "Resetting sync data will erase all Conacts and Calendar data from your Apple Watch before re-syncing from your iPhone".


Once I did this, all the extra entries from shared calendars were gone and over the next several minutes, everything rolled in and it's exactly as want it.

This seems to be the only thread that mentions the "Reset Sync Data" button in the General section of the Apple Watch app on iOS. I have looked high and low for more information about this, but there really is nothing at all about this anywhere online (so far).

My biggest question is how exactly do I use this feature? Yes, it sounds simple -- just push the button. And yes, I would love to be able to push this button to use this feature!


But, pressing this button seems to have literally no effect at all (except to gray out when I press it, until I let go of it). In other words, whenever I click the button (screen shot on the right), it just grays out to indicate that I've depressed it, but it doesn't give me any feedback to say it actually worked!


In other words, the button doesn't change state unless I let go of it. So basically, it feels like a button that's disconnected, and thus has no effect.


When the folks who have successfully used this feature have clicked the button, did it actually give you any feedback to say it worked? The other buttons have the obligatory ellipsis ("...") at the end to indicate that there will be a confirmation/details dialog -- and in fact, if you click them, you do get prompted for confirmation. But this button (Reset Sync Data) doesn't have an ellipsis, and doesn't give any feedback when pressed (aside from graying while you're holding it down).


Are you saying you get different behavior from this button? Both of the posters above said they were able to get this to work. But -- my question is, "how?" (And, believe me, I am fully aware how stupid this question sounds!)


When I press the button -- and then go to Calendar on my Apple Watch -- the visible events are not cleared like you say above! The button basically has no effect.


Now, I can make the Calendar events go away en masse by simply going into my iPhone's Calendar app and de-selecting (disabling) the specific calendar in the settings. However, that just has the effect of hiding that calendar's events from the display (as well as on the watch). But, they all come right back to exactly where they were as soon as I re-activate the calendar (by checking it within Calendar on the iPhone). But at this point, it's not re-syncing the data, it's just re-displaying what's already been synced. And in my case (and many others'), that data is stale and not getting correctly updated like it should. So it just re-displays the old, stale, broken event data, and won't just do what I want (!!) which is re-push the latest state as it is on my iPhone, down to the watch!


No matter how many times, or for how long, I hold down or press the "Reset Sync Data" button in the Apple Watch app on my iPhone, it simply will not replace the currently broken and out-of-date calendar details with the up to date ones.


As I've posted other places, it does eventually show me the correct calendar -- but often on the order of 10-12 hours after the fact. When it's no longer useful. I don't understand why I can't force it to update now, when I need it to be the latest (i.e., during the day when I'm running around from meeting to meeting and never sure if meetings have been moved, cancelled, or if new meetings have been added).


This should not be so difficult and confusing. Anyone?


Thanks heaps.

I worked with Apple Support yesterday to find possible reasons for my calendar data not syncing correctly. What seemed to work was reducing the number of calendars I have to choose from with my work google apps-based email account. I had 25 calendars listed under that account. I dropped the number of calendars down to about 4, reset my watch (again :-( ) and it now seems to be working.


The upshot is that the phone-to-watch sync choked when there were too many calendars in an account. Further, just selecting a few calendars to show didn't work. I could actually see the non-selected calendar data displaying on the watch.

Can you confirm -- how did you actually "reduce" the number of calendars it needed to sync to the watch???


I am missing something here. Do you mean, on your iPhone? Did you change this in the Calendar app itself, on the iPhone, or in the Settings?


There are several places to do various things, so here's what I have (and I'm getting nothing) so any pointers on what you're doing differently could help me and others resolve this. (Note: I'm also using a calendar via a Google account as you are, so I think if I can copy your set-up, my problem could actually finally be resolved.) So far, I've only ever seen "No events this week" in a frustratingly uninformative Apple Watch experience. :-(


On iPhone:

* In Settings > Mail, Contacts, Calendars > Accounts > my Google account > Calendars slider switched to "on" (all other sliders off)

* In Settings > Mail, Contacts, Calendars > Calendars > Sync is set to "Events 2 Weeks Back" (minimum value just in case)

* In Settings > Mail, Contacts, Calendars > Calendars > Default Calendar is set to my primary work calendar in the Google account

* In Settings > iCloud > Calendars slider switched to "off" (no iCloud calendar; I've tried both options, no change)

* In Calendar > Calendars (bottom button) > unchecked all calendars except my one primary work calendar in the Google account.


Or did you do something in iCloud, either on your Mac or on your iPhone, or on the web? It's hard to figure out whether the Apple Watch is displaying the content of my iPhone's built-in Calendar app, or if it's displaying its own version of the iCloud calendar somehow. If the latter, I can't work out how to tell iCloud to subscribe to any real calendars aside from the two pre-loaded calendars you can subscribe to in iCloud (birthdays of friends, and national holidays).


And of course, there are absolutely no useful settings on the iPhone "Apple Watch" app relating to Calendar. It just shows the alerting options, nothing about which account to display, and certainly nothing as fine-grained as which calendar to display (within the accounts). Note: I hate the idea that I have to sacrifice my full iPhone experience just to get it to sync to my watch, but I'll do it, I suppose, if there's a way to make it display anything more than "No events this week" which is driving me insane. :-(


Also, do I have to wait some undetermined period of time to even test any changes out? How do I know if the changes I made will eventually actually propagate to the watch? It's impossible to understand the model here: whether it's my iPhone that's loading the data, or if it's a back-end iCloud service that's polling the feed periodically. On the iPhone, there's also the setting to say whether to use fetch or push, but of course for these types of feeds, it only offers fetch or manual. So that doesn't really tell me much. :-(


Thanks for any pointers.

Update: After making the above changes (deselecting all but my primary work calendar from my Google Apps account on my iPhone), my watch still shows absolutely nothing.


So, I re-read all the text, and started to realize, you may actually be talking about Google Calendar itself (as opposed to the Apple iPhone or iCloud subscription to that calendar). I am now guessing that you mean there's a bug (or limitation) that is breaking syncing specifically to the watch, accounts that themselves actually have too many calendars subscribed within them.


For those of you who don't know what I mean: this only applies to people who use Google Apps in particular (which many companies use, including mine). It turns out that Google Calendar has a feature that lets you see others' calendars overlaid with your own. Let's say I happen to work at a big enough company that there are literally thousands of calendars to potentially subscribe to. Let's say that I have been working there for over 10 years, and I have over time accumulated a huge list of subscriptions to other people's calendars, since just *once* long ago, I happened to view each person's calendar overlaid with my own (which Google Calendar makes ridiculously easy -- there's no explicit subscription feature, you simply search for their calendar right on the main calendar view, and it auto-completes to all the employees of the company that uses Google Apps for their calendar and/or email), and *blammy* you are subscribed the second you hit the tab key (even if you then hide the newly-subscribed calendar right away).


So, when I went to look just now in my calendar (on Google Calendar for my company's domain), I found that I was subscribed to upwards of 150 calendars (!!). The reason I figured this out was because the original poster here mentioned having 25 calendars listed, which is far more than I had just in terms of my own calendars (i.e., different shared team calendars for groups I work with, etc.). And I thought, "Why would anyone have 25 calendars?" Then I remember this crazy feature of Google Calendar where it auto-subscribes you just because you looked at someone's calendar. And so now I'm guessing this is exactly what's going on in my case -- at least, it sure makes a lot more sense now that it may be the problem.


So why haven't I already tested this theory and come up with the answer? Well, unfortunately, it's non-trivial to unsubscribe from calendars (despite it being trivial to subscribe in the first place). There may be a way to script it, but failing that, you have to manually unsubscribe from each calendar, and click confirm each time (there's no default so you can't just hit enter, ugh!). So, since I have literally 150 calendars or so to go through, I thought I'd post my breakthrough first, in case the original poster sees this before I'm done. I'll post again when I know for sure if that was it.

Sorry you are having so much trouble with your Calendars.I am using iCloud and Exchange Calendars and can see current and future events for all but my 2nd Exchange Calendar (I think this is definitely a bug).


I just wanted to point out that, despite the "Mail Days to Sync" setting for my Calendars on the iPhone, the Watch does not show any past appointments. It only shows today and future events regardless of whether it is an Exchange or iCloud Calendar (I do not have any Google Calendars).


Good luck.

Yep -- that was it (I think). Unblocking it to actually sync to my watch had the unintended consequence of then triggering another issue (read: major bug) with "invitations": for some (stupid) reason, it decided to notify me for *every* unreplied invitation going back however long! So, for all those instances of repeating weekly meetings that I have not replied to, it synced them all to my watch as notifications (seemingly ignoring my iPhone preference which I was mirroring by default, which is to ignore invitations from my work calendar on my phone). Weird. So it took *forever* to eventually start showing the data (it really caused other problems in the interim; my watch was having serious problems doing anything that needed to communicate with my iPhone during that time).. but once it finally started presenting the alerts for all the previous invitations (I mean, we're talking about a hundred at least), I realized that was the problem now (flood gates = open).


So, I went back into the Apple Watch app on my iPhone (in somewhat of a panic) and edited the Calendar settings to explicitly disable alerting on invitation -- and voila! After a minute or two of waiting for it to re-sync, it seems to finally actually work!!!!!!


Thanks.

I am also having calendar sync issues. I have one Exchange (Office 365) calendar. Most appointments are syncing but some do not. The appointments do sync fine to on my iPhone 6. This effectively eliminates the convenience of the watch because I cannot trust its accuracy and therefore need to pull out the phone anyway. Please help.

Reducing the number of calendars being synced doesn't apply to me - I only have 2 (work [exchange] and personal [google calendar]). The meeting that wasn't being synced was on my exchange calendar.


The changing of the event to private did force a re-sync of the calendar data between my apple watch and iPhone. I changed it back to public after the re-sync was complete - however this appears to have queued 2 "15 min warning" notifications to occur (which just happened now).


This is definitely a bug but at least there is a work around (for now).


Also for folks that do this - be aware that if you have other invitees on your meeting it will trigger (potentially multiple) meeting update e-mails to be sent out to everybody.

I have the same setup - a personal Google Calendar and a work Exchange calendar. Seeing loads of problems with the Exchange calendar not syncing currently. The phone is showing the correct appointments but they are not being synced to the watch, which continues to show out of date appointments, appointments that have been deleted from the iPhone and doesn't show newly-added ones. Force-closing the Calendar app on the watch doesn't help, neither does restarting the iPhone or the watch.


I added an appointment to my Exchange calendar from my phone and it immediately appeared on my watch, so I wonder if it only affects events that have synced to the phone from the Exchange server?

I just had a chat with Apple Support who raised a ticket. They said the more people who raise issues with them the better, so I strongly recommend everyone experiencing this problem fills out the feedback form:
