I got the pixel 6 about 2 months ago and everything on this app was fine until about a month ago. For no apparent reason my voicemail tab disappeared. After going through all the settings to bring it back without luck, I go to the play store and I decide to "uninstall" the app. It actually fixed it! What happened was that it actually went to an older build. For some reason, when updated, it looses the voicemail tab. Unfortunately it's not a permanent fix. The app updates automatically.
