Why does apple watch no longer record my sleep?

This is happening to me too. Watch is charged, sleep tracking on, wake up with no data. What’s the point of an overpriced watch if its features ‘sometimes’ work? How is one supposed to use this for a sleep study if it randomly stops recording???

I bought a Series 9 two days ago and sleep stages are empty, I see "No Recent Sleep Data"

Sleep app only shows Time Asleep and I'm not sure how to fix this.

Need solution to this ASAP.

Over the last 2 days my Apple Watch Ultra has stopped recording my sleep. I haven’t changed anything in the settings it just stopped. I’ve turned off & on on both the iPhone and the watch but it still won’t record my sleep data? Heeeelp….

is automatic sleep focus enabled on both your watch and your iPhone?

If so, try and restart your watch and iPhone to see if the issue is persisting

Have your problems fixed? I have the same issue

Did anyone get a surefire solution to this? I am on my second apple watch (replaced under warranty partly due to this exact problem). I am beyond frustrated…

Did u get the sleep working ? I have same problem

Exactly the same problem. 10 week old apple watch was working perfectly, now no longer records sleep. Can Apple respond?
