Since updating to Mac OS 13.1, VoiceOver no longer works at login even though I have it turned on in System Settings>Lock Screen>Accessibility. When I restart my Mac, VoiceOver announces "Authentication in progress" and then locks up. I have to turn VO off and on to use it at login.
I have a 2020 MacBook Air M1. I know of at least one other person who is experiencing this, and it has been reported to Apple Accessibility.
Also, sometimes VO seems to have focus issues with System Settings. For example, when jumping from the table to the scroll area, VO sometimes locks on the first item. You can easily get around this by pressing tab sometimes to move to the next option.
These are minor items but a little annoying.
