Sleep Mode not working on Apple Watch s3
I upgraded my Apple Watch Series 3 to watchOS 7. When I turn on the sleep mode on my watch, display is suppose to dim, only date and time should be visible on watch screen and screen should be locked.
None of it is happening. I can see sleep mode icon on my watch but screen lits up, watch screen doesn’t change to display only date & time. Watch screen is not getting locked. It lits up when I move.
Any help will be appreciated!! Thank you!!
