It started a few updates back and I can’t seem to stop it happening. I check periodically that the do not disturb is off then find I’ve missed calls and haven’t noticed messages because the alerts have been silenced. Once I realise and check settings the damn do not disturb is switched on again. I have do not disturb set from 11pm to 7 am so out of these hours there is no reason for the do not disturb to be on and yet it is. Other then not setting do not disturb at all I am all out of ways to stop this happening. Is anyone else having this issue?
