Sleep screen no longer works

Since I got the apple watch I used the sleep focus mode with the sleep screen function showing only the time.

It doesn't work anymore.

I tried:

• Disabling and reenabling all sleep and focus settings
• Deleting and reinstalling sleep app in the watch
• Rebooting both the app and iPhone

I saw in a March a similar thread that someone suggested to disable Always On feature. That's not the solution. The "Sleep screen" not just dims the screen, but locks the watch and disable the wrist gestures until you hold the crown for a few seconds, also allows you to see the time.

I do not need help setting up the sleep focus mode, sleep schedule, neither synching state with iPhone. I had done this before and it worked, it doesn't works now, this is a bug.
