Hi RS32,
The following steps address what you're describing specifically, and should provide a solution as you may have disabled Sleep Focus for that sleep schedule.
"Turn off your Sleep Focus for all sleep schedules
- In the Health app
, tap Browse at the bottom right, then tap Sleep. - Scroll down to Your Schedule, then tap Full Schedule & Options.
- Turn off Use Schedule for Sleep Focus.
When this setting is off, your sleep schedules remain in effect, but your Sleep Focus doesn’t automatically turn on. You can turn this setting on again at any time."
