Sleep mode focus problem on WatchOS 8
Hi- I recently updated to iOS 15/watch OS 8. I'm trying to track my sleep. On my watch I go to the control center and press the moon and enable the sleep focus. However, my watch does not dim the way it did on watchOS 7, and required me to turn the crown. The only way i can get the screen to stop lighting up is if i turn on the sleep focus and also theater mode.
Is the issue that i'm required to create a sleep schedule? I always just manually activated sleep mode on WatchOs 7 and turned the digital crown when i woke up.
Please advise
Apple Watch Series 6, watchOS 8
