@ryanheise I am happy to look into this more, but I'm unfamiliar with native iOS so I got lost when trying to debug. Do you have any tips or ideas where I might start my search?

[ryanheise]

Thanks for taking an interest in contributing! These sorts of things typically come down to reviewing the Apple documentation for the APIs being used and checking in stack overflow for similar issues in native iOS apps.

The same issue here .

[EthanBarlow]

@virmana Have you observed this issue on both the simulator and a physical iPhone?

[virmana]

@EthanBarlow I just tested the app on simulator, does it work well in physical iPhone?

[EthanBarlow]

@virmana I do not have a physical iPhone that can run the latest version of iOS. I am currently stuck with an iPhone 6s that runs iOS 15.7.2

[leonidlist]

Just tested this behaviour on physical iPhone with iOS 16.2 installed and everything works as expected

[ryanheise]

Thanks for testing, @leonidlist .

@EthanBarlow can you get a beta tester to test your app on their physical phone through TestFlight?

[virmana]

Thank you @leonidlist .

So as I see it is mainly related to emulator, because on emulator (iOS 16.1) I don't see action buttons on lock screen/dynamic island @EthanBarlow @virmana

[EthanBarlow]

@ryanheise I will work on getting a beta tester to check this behavior, and I am expecting to get a new device that will support the latest OS allowing me to perform the test myself. @leonidlist Thank you for testing! Also, I will update my Xcode installation and test on the simulator with iOS 16.2 since right now I am on iOS 16.1.

[EthanBarlow]

I just set up an iPhone 11 running iOS 16.2 and found that the bug described is not occurring on a physical device. It appears to be a problem with the iOS simulators. Thank you @virmana, @leonidlist, and @ryanheise for your input. I will close this issue since it's not actually a problem on physical devices running the latest iOS (16.2 at the time of posting).
