iPhone 11 Pro Lock not working
I just purchased a new iPhone 11 Pro. The side lock button rarely works to put the phone in lock mode - occasionally does, but usually that doesn't persist. Same with the 30 second auto lock. I found the support article from 2020 suggesting restarting (no help) and reinstalling iOS from a computer (no help). The buttons all function fine, just the lock feature not working.
