I have a student that I am teaching and his Apple Watch will not mute the ringer or alerts using the mute feature through control panel? he has also tried using the theater mode and mute mode together, still phone rings come through and message notifications come through And the ringtones as well come through. He needs this feature for meetings when he does not want the watch to ring or notifications to make any sound. for the time being I’m going to recommend that he use do not disturb if we can locate this under the control panel. Can someone help?
