I have my sleep schedule set to end at 9am for the few days I actually get to sleep in, but usually I'm up well before that and I manually disable sleep mode via the quick toggle. for the last week or two (probably coinciding with 18.22) the watch will re-enter sleep mode a few minutes later. if I manually exit again it just re-enables a few minutes later, so I am unable to make the setting stick until 9am hits. the problem has now persisted into 18.23.
on a similar note, is there any way to disable sleep schedule? I remember it asks about it during watch setup, but I can only find a way to edit the times, nod disable the schedule altogether.
