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

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.

After Update my iPhone 6 on iOS 9 and Apple Watch on watchOS 2.0 calendar stopped sync from Phone to Watch. I have 3 of them - iCloud, Exchange and Google.

I tried many times disable all calendars in iPhone and after some time re-enable them also Reset Sync data on Apple Watch. Not working.

Tried unpair and repair Apple Watch with iPhone. Not working.


I am quite frustrated with it. Hopefully there will be some quick fix from Apple or Microsoft will release updated Sunrise Calendar for Apple Watch with complication soon.

Yeah this bug is an absolute nightmare. I have iCloud, Exchange and Google calendars. I have removed all but iCloud and I did a hard reset and still nothing. Reset Sync Data does nothing. The next thing I could try is to completely reset the watch and not restore from backup but I am not sure if this is going to help me.


The really bad news: I am on the Fantastical beta program and the native watchOS 2 app they are working on uses the events in the calendar on the watch so Fantastical is no longer useful as a workaround :(

+1 for me.

Upgraded to Apple Watch 2.0 and the MS Exchange calendar no longer syncs to the watch. Email is still syncing.

I have an MDM profile on my phone, as several others have noted this seems to be a common theme.

I rang apple tech support, got escalated. The technician he said he did not think this was a trending issue. Please help make it a trending issue! log your issue!

I asked if I could roll back to Watch v1 where calendar was syncing file - nope.

Very frustrating, this is why I got the watch in the first place.

Come on apple!

Yes I've been wondering if the MDM is the problem. I also have one. I happened to get a 6s today and I set it up as a new phone and set the watch up new (again) too and of course everything works fine right now with just iCloud calendar. I was just about to add my corporate stuff on with the MDM but this time I was planning to avoid using the Exchange mail/calendar stuff. However now I'm wondering if I should avoid the MDM.

Well, I got a call back from Apple Enterprise Support!


Apple does acknowledge an issue with MDM profiles which have the restriction "Opening documents from managed to unmanaged apps not allowed" if you have this then calendar entries are not synced to an Apple Watch that has been updated to v 2.0


So my advice is if you have such a profile then do NOT update Apple watch to 2.0 until this issue is sorted or your companies profile is changed. Because if you do there is no rolling it back.


If you have this issue Please tell apple about it, they only fix things that have a high volume of impact.

Dan

I am having the same issue as well - I have a corporate MDM profile (Airwatch) installed on my phone. All was working fine...upgraded to ios 9 on my phone...all was still fine...upgraded to watch OS2 ... all my calendars stopped synchronizing. I do get some calendar invitation/change notifications, but the actual event doesn't get persisted into the calendar on the watch. In my opinion, this has taken away the most useful feature of the watch (which is a little light on differentiated use cases at this point). Very unfortunate and I hope they address it quickly (although maybe that time has already passed).

I had the same issue: after updating to WOS2. I lost all calendar events. After 2 sessions (amounting to about 4 hours) with tech support they gave up and exchanged the watch. The new watch, running WOS1.0.1 works fine - syncs Microsoft exchange, icloud and google calendars even with MDM on the iPhone. I asked if this was a common issue and was told it was not. Apparently it is.

I will not upgrade to WOS until I am sure this is fixed!

APPLE: Please fix this in WOS2.1

While it doesn't solve the issue, I found a way to faster re-sync the missing calendar events directly on the watch and not using the watch app. With the calendar app open, press the side button (below the crown) and hold until the turn-off screen appears. Then press and hold again until the calendar app disappears and is replaced with the home-screen. Restart calendar and magically all events are synchronized (at least with my company managed exchange account).
