Pixel users are experiencing significant app malfunctions on Android 15, particularly with Gmail, due to issues stemming from a recent Google Play update. Many users report that their devices indicate "Google Play Services is not supported," rendering both first and third-party applications inoperative. Error messages related to Google Play Services being unavailable or outdated have been noted, and the problems may extend beyond Pixel devices. Users have attempted various troubleshooting steps, including factory resets, with mixed results. Some users are advised to opt out of the Google Play services beta and restart their devices, but this solution has not been universally effective.
