I am trying to delete my personal voicemail Greeting. When I got the new Google Pixel 6 plus, my old voicemail Greeting from 12+ years ago returned. I have not heard this voicemail Greeting in YEARS. When in voicemail menu the only option is to record a new one but I would rather use the standard voicemail greeting. When I change it to the standard voicemail greeting, It works BUT eventually my personal voicemail Greeting from 12+ years ago returns on its on..so I have to keep going in and changing it back to the standard greeting every couple of days..is this a glitch?
