I was using my phone for an alarm while I was away in asia, and I've never had any problems with my regular do not disturb for one hour whenever I turned it on, but now my sleep mode from 9:00 in the evening to 7:00 in the morning shuts off at 9:00 so I get audible notifications making the sleep mode obsolete. The only way I found so that it works properly is I have to change my standard Do Not Disturb mode from my 1 hour relaxation when I wanted during the day, to be, do not disturb until I turn it off. Very annoying and it must have been an update or something for all of us to experience these problems. I've been working on a solution for weeks now, and the only way to stay silent is to change my do not disturb default of an hour to be, do not disturb until I shut it off.
