Not sure if this is a feature request or a bug report, honestly, as I would think if Sleep as Android is capable of turning DND on, it’d also turn it off at the end of tracking, but then again I don’t see anything in the settings saying that that will happen
When I wake up and slide the slider / rate my sleep, DND mode still remains on unless I remember to turn it off manually.
I’m on a Galaxy S9+, so that means Touchwiz in case that makes a difference (I read in the other thread that DND mode may work differently on Samsung devices).
