After upgrading to Android 11 I now often notice that the mobile data is broken. I can fix it tempory by activating/deactivating the flight mode. Some hours later having the same issue again. Maybe this is usefull: meanwhile I have been connected to a wifi-network. “On the road again” mobile data is broken.
