My Apple Watch SE 2nd gen watchOS 9 doesn't register my activity

Cause 1 of 3: Your Apple Watch is too loose on your wrist

If your Apple Watch is too loose on your wrist, some of the watch sensors will not function correctly.

Solution: Adjust the watch strap so that your Apple Watch is neither too loose nor too tight on your wrist.
