I have an S10+ which continues to play my text notification sound even on Vibrate Only mode. I have checked sound settings and made sure that Ringtone, Notifications and System sounds have the bar all the way on the left with the strike-through icon indicating that they are muted.
I don't know if I am missing a setting somewhere else. Has anyone experienced this? I am on the latest version of android One UI 3.1, Android 11, Security Patch Level July 1st, 2021.
