Samsung voicemail fix

These steps fixed the problem on my Samsung s22 Note with the "visual" voicemail app not working with Xfinity.

Go to Settings > Apps > Visual Voicemail or Voicemail. Click Force stop. (This was important!)
Then click on Storage. Do Clear cache and then Clear data.
Then go to Settings then open General Management look for reset and reset mobile network settings only.
Then go back to your phone home screen. Open Visual Voicemail. It will then go through its setup and ask for the permissions it needs.

Note: I had to boot my phone to get the last voicemail setup step to work.
