Two iPhone SE2020 units have lost the phone and Facetime incoming call ring after updating from 18.7 to 26.x during the holiday break. The Volume button is set to max, there is no Focus setting, there is no Call screening, Bluetooth is off, the ringtone setting works, and an update to 26.3 beta did not fix it. The phone does display Missed Call details as well an incoming call notification banner plus an incoming call notice on a nearby mac when in the office.
The only thing that fixed the issue on one phone was to wipe and startover with a fresh 26.2. However, the phone on 26.3 beta cannot be wiped and restored from a Mac running 26.2 due to an insufficient resources error message.
