Hello I just recently purchased the galaxy watch ultra.
My last watch was a watch3 so I understand alot of changes has happened between now and then.
When I would turn on sleep mode on the watch 3, it only affected the watch. My only use for sleep mode I having the watch screen stay off when moving in bed. I don't want DND to turn on on my phone. Ive already turned sync modes off.
You can turn off sync modes with phone in the Wear app watch settings. If you want the modes synced because you use other modes, just edit sleep mode on your phone to delete DND. My experience has been that DND always syncs between the watch and phone regardless of whether you sync modes. So your best bet would be to remove DND from the mode, or turn off DND after you turn sleep mode on. You can also edit DND in sleep mode to let the calls and texts and notifications you want to come through without it affecting the settings for normal DND. Rach mode's instance of DND can be set differently and remsin separate than your main DND parameters.
