I noticed the other day when I hit the “Set as current Watch Face” button in the apple watch app on iPhone, nothing happens at all. further, I added a new watch face in the iPhone apple watch app, and it doesn’t show on my watch in the list of faces I can switch between. then I also noticed that my omnifocus tasks won’t sync on my watch. everything else I checked worked, such as complications are pulling data, getting notifications, even things like phone calls ringing on my watch and siri still working. it’s an original ultra, running 10.1; haven’t updated to 10.1.1 yet. note I also have an apple watch series 5 which I use as my sleep watch. need to see if that one is controllable from my phone or not, I haven’t checked that.
things I have tried: reboot phone and watch, no change. toggle airplane mode on phone and watch, no change. reset apple watch completely, then set it up again and restored it from backup. that fixed it for a day or two but now it doesn’t work again. and the restore copied a bunch of my faces. so now I have 58 watch faces but almost all are duplicated, and some are duplicated 4 times. so in reality I probably have 25 unique faces.
edited to update WatchOS version
Might be worth updating the 10.1.1. Whilst it’s not likely that the update itself will fix it, it might reset whatever is causing the issue.
You can also try (on your iPhone): Watch app - Settings - General - Reset - Reset Sync Data.
I don’t believe this setting removes anything other than what is specifically mentioned on the page, but do your own research to make sure!
If you’ve got the Ultra and have the Cellular enabled, it’s possible that the working areas are doing so independent of the phone, either through your carrier (phone calls) or iCloud.
What happens if you turn off the Cellular on the watch?
I turned off cellular and wifi on my watch, and was able to send an iMessage, and the weather app pulled weather data. so the data conduit over bluetooth is working.
last night I was able to update my phone from 17.1 to 17.1.1.
I also checked on my series 5 sleep watch; that has the same trouble. data in general works, but config items like watch faces won’t copy between phone and watch. (couldn’t set current watch face from phone either).
today I’ll get the watch updated to 17.1.1 but I’m not optimistic.
Got the ultra updated to 17.1.1; no change though.
So I read that watchOS 10.2 will bring back an option to swipe between watch faces like before. Thinking that I may not be able to set that option from the iPhone watch app in my current state, I decide I would reset both watches and only set up my newer one for now to see if that helped. So one last time I tried to set the watch face from the watch app on iPhone. This time it worked. I haven’t tried to do anything else since my last post. So I guess that’s great. Hope it doesn’t stop working again!
