I have a dnd setting (sleeping time) from 10 pm to 7 am. It used to work correctly, I did not receive any notifications during the night. For some time now (I think since 5.25) it stopped working. Watch (vivoactive 3) never goes into DND mode and the notifications are sent 24/7. I'm already on 26.1 but no change, still no automatic DND mode during sleeping time.
