Mi 5 Pro user on 6.11.10 dev rom in English language. (I am only posting the bug here because the update for my model has been suspended for two weeks.) DND fails intermittently and plays sounds on calls and notifications out loud. I don't wanna set my phone to "Silent" for all my Fitbit notifications are diabled in the mode. I have to set on Custom mode to apply to all calls and notifications. How come there is "None" option under Exceptions, and why would anyone select "All" exceptions in DND mode?
