Apple Watch Calendar not Syncing to Watch Face

Having a similar, but slightly different issue. Have an IPP11 and a S5 watch. If I use the Calendar app on my watch, I can see all my iCloud Calendars on the watch/complication. But, if I use any third party calendar app, they can see my calendar events on the phone, but the apps on the watch cannot see the iCloud calendars. After testing, noticed there seems to be two type of iCloud calendars. One strictly in the cloud, and one that’s copied on the actual phone. What I found is if I toggle the iCloud Calendar switch to OFF in the iPhone settings, I get asked “What would you like to do with the previously synced iCloud calendars on your Phone? KEEP ON MY iPHONE or DELETE FROM MY iPHONE”. If I select KEEP, it creates a local copy of my iCloud Calendar entries, and then suddenly, the apps can see all the calendar entries. If I look at the calendars available in the Apple Calendar App, it now shows ON MY IPHONE listed above my iCloud Calendars, instead of showing them with an ICLOUD header. However, when I go to turn the settings switch back on, it asks me if I want to merge iCloud with the local copies, and when I do that, they all disappear from my watch again (except from the Apple Calendar app).

So the watch is not able to see iCloud calendars that are truly housed in the cloud, and which aren’t saved locally on the iPhone. I suspect this might be what is going on for everyone else as well. Test it out by turning of the switch, and then selecting KEEP, and see if the events show up on your phone before you turn the switch back on.

I tried that too, and still no luck. My issue is slightly different. The Apple Calendar app can see all my events from my iCloud calendars on my phone and watch, but any third party calendar apps (tried 3 of them), cannot see the iCloud calendar events on the watch. Only on the phone. On the watch, they can only see calendars loaded directly on the phone (like Apple Holiday calendar). I confirmed this when I turned off calendars in ICloud settings. When it ask me if I want to keep a copy on the phone or remove the data, if I say keep, it creates a local copy of the events on the phone, and then they appear. As soon as I turn Calendars back on in iCloud settings, and I select Merge the combine the data on the phone with either data in iCloud, everything on the phone is wiped and all events are in iCloud, and then the watch stops seeing the events.

Super frustrating!! My last attempt will be to unpair the watch and set up as new (instead of from a backup).

If that doesn’t work, I’m stumped as to what else to do. I’m thinking this has something to do with Apple’s new directive around how apps should be independent from the phone and run natively instead of just a ported version from the phone, and how it should get data, but I can’t prove it...

That sounds really frustrating. One thing I was going to consider doing next (for my Siri watch face missing upcoming events issue) was to just use my Google Calendars instead of iCloud Calendars to see if that works. Have you tried this approach?

Regrettably, I am using google calendars. It doesn't seem to matter anyway. Both iCloud and Google calendar data are suffering from this issue. Since my re-pairing of my watch it seems to be…better. But it's only been a few days.

Hmm, what are the 3rd party calendar apps you said you have tried? I only use Apple Calendar (with iCloud and Gmail/G Suite calendars) on my Macs and iPhone/Watch so maybe if I go into this with a fresh set of eyes and try them myself I might be able to duplicate your issue and/or find a solution.

I really can’t. I have 8 different iCloud calendars I use. One each for myself, my wife, my two kids, my parents, our school schedules, travel events, etc. Some with years of past and future events, and some shared out to other iCloud accounts too. It’d be a major pain to try to move stuff over.

I tried Calendar 366, Calendars (by Readdle), and Fantastical. All three with the same results. At first, I thought it was a bug in the main app I use (Calendar 366), and even was working with the dev to diagnose and test beta versions he made just for me to try to track it down. Then I realized it was an apple bug when the other apps did the same thing. All except for the Apple calendar app.

I have had this problem on and off— both with iCal and Google Calendar. I've had to unpair my Apple watch 4 a number of times which is a real pain, but then it syncs and displays my calendar events which is the main reason I got this watch. Interestingly enough, Google calendar syncs more reliably than ical.

My watch stopped showing events a couple weeks ago. I have read all the fixes and done EVERYTHING suggested, multiple times. Still does not show events from my calendar. Does anyone have any new advice to give on this ridiculous problem? Thank you

Google Calendar syncs more reliably with my watch, too- unpairing and pairing again worked. So did turning on and off the calendar toggle in iCloud which was much easier than unpairing. I have had this problem with my Apple Watch 4 at least 4 times since I got it right after the Apple Watch 5 came out. I bought the watch for its calendar sync, so this bug is really problematic.

well folks, I never had this problem with my iWatch series3 until the battery died. So my wife got me a new iWatch series5 2 months ago, and I started to have issues with my calendar on my watch. My iphone calendar was not mirrored to my watch, even though all the setup buttons were set properly on my watch app on the iphone.

Tried everything possible for 2 days ... unpair-pair ... reboot .. factory reset ... clear icloud calendar sync and then sync again ... etc etc .... I am an electrical Engineer so I am used to trouble shoot and debug electronic devices ... but this one was really not working at all. I read all the possible forums on line and none of the proposed solutions worked. I finally try to get hold of apple support ... got online with one first person .... totally USELESS, that person was completely clueless ... seemed it was her first day at Apple ... then got a second person .... that one tried everything he had been trained to do, following the checklist ... but quickly realized that he was going nowhere ... when I said that I was going to return the watch because apple cannot even figure it out ... he sent me to his supervisor .. and I finally talked to someone who knew way much more than the other 2. but but but ... we spent almost 3 hours on the phone, he made me try everything ... which I had already done for 2 days ... no success ... he made me take screenshoots of my iphone and my iwatch ... sent them to him so he could pass them on to his engineering support team to debug the issue. That guy was very serious and accountable. he contacted me back 3 days later saying that his team was still working on the problem. Luckily, before he came back to me with an answer, my calendar started to sync and so far it has been syncing properly for about 2 weeks. I do not believe in magic and luck ... so Bottom line is that I think Apple did something with my icloud sync issues. They never told me but this is the only explanation. it is not a watch problem, it is not a watch app problem. it is an icloud calendar problem. I wished that Apple would fix that indefinitely because I saw so many people having this problem starting in 2015 and 5 years later they still deal with the same issue. Good luck everyone. And Apple need to do a better job for their expensive products ..

Update re calendar sync issue.

After turning iCloud off and on again I got calendar events showing on my watch again. BUT... after a few hours it disappeared with the ‘no events today’ showing . I turned iCloud off and on again but that doesn’t work anymore. I guess it’s going to be a lengthy Session with Apple support. Not happy.

That is my experience, too @Apulah -- once I turn off iCloud and then back on, calendar event son my watch start to appear and then within the hour totally disappear again. I simply want to mirror the events that I see on my iPhone!

Same here. It showed up for part of a day then went back to No More Events. I was going to buy a new Apple Watch but will not until this is fixed. It's ridiculous. Did absolutely everything suggested and nothing works to restore the events.

I have the same problems- reset sync data, unpair, new watch (Gen 5), iPhone 6s Plus.....multiple check-ins with support, etc. The calendar will sync for a day or two, and then stop syncing. One assistant suggested unchecking some of my many calendars, which worked for a week, but now O have the same problem, “no more events today” when I have events. I am looking forward to the next iOS update.
