While it is much better, I still have the stop of the timer with iOS 16.1 Beta 3 from times to times (but it is hard to reproduce as it is quite random) Playing with the phone by going to the some pages after, some pages before, locking the screen, can make the issue appear. But changing the page again will make the timer continue at next display.

16.1 Beta 2, same problem.

Indeed, the problem is not fully solved on iOS 16.1 beta 1.

OK ... so ... it seems that the public version of iOS16, being the same as RC1, still contains the bug. Let's get ready for support emails from unhappy customers, and bad reviews from the App Store 😞. (I read that iOS 16.1 is scheduled for November...)

This is so bad. I'm preparing a new (degraded) version of my apps in case they don't fix it.

From another related post: @ricob : "Hi, we are aware of the issue. Please follow the iOS 16 beta release notes for updates on when this will be fixed."

Feedback assistant says that there are more than 10 recent similar reports, so at least they are aware about the problem (since someone merged them). I'm also worried about the bug not being fixed before the non beta release, but this is a good sign.

This is bad news... :( I can confirm this too. I wish Apple developers would read their forum / submitted feedbacks (which we spend time and energy on), and just say if the bug is under their radar. OS regressions are the worst, and put us in a very awkward position with our app users.

Thank you. Here is my feedback number FB11364016 as well. Strangely, the problem does not appear on iPad (with iPadOS 16.1 beta 1 (20B5027f), released the same day). So perhaps the implementations are different according tot he device, or the bug is already fixed.

Same problem on Safari. On Chome, it works OK.

add me to the list

Same problem. File → GPU Selection → Prefer Integrated GPU (and simulator restart) does not work for me. I'm on Catalina, iMac 2017.
