Control Center Focus Button Not Working
Similar to many other users, I have been experiencing an issue with my Focus button in Control Center. It is identical to this entry from over a year ago:
Control Center Focus Button Not Working - Apple Community
Specifically, when I try to start Do Not Disturb via the "moon button" on the Focus button in Control Center the button toggles between gray and dark, acting as if it is doing something but not actually enabling DND. If I long-press the Focus button and enable DND there, then I am able to toggle the moon button on/off in Control Center. The icon goes from white moon on gray button to purple moon on white button. HOWEVER, if I turn DND off it reverts to the disfunction again and only works by long-pressing the Focus button.
iPhone 13 Pro, currently updated (fully) to iOS 16.5. Restarting does not fix the issue. I have restarted, force-restarted, shutdown and restarted, reset all settings, erased the phone and restored from iOS backup, both over the air and via Finder on my Mac. It also occurred on my prior iPhone 13 Pro. None of this has changed the behavior. I am saving the scorched-earth technique of fully wiping the phone and setting up new for my final option..., but I think I'm there.
As an aside, frequently I am not receiving notifications that I have (correctly) configured. It feels like it could be a Focus-related thing, but I can't tell.
