Apple Watch Ultra not Tracking Sleep Stages for 4 months

When I first got the Apple Watch Ultra all tracking was fine, I had a detailed analysis of my sleep every night.

Since late September, around the time I lost my iPhone 13 Pro and switched to the iPhone 15 Pro, I have only had basic data being tracked, even though I have the setting to monitor sleep tracked in the watch app.

What could be the issue and how can I get this data back?

iPhone 13 Pro, iOS 16

Sleep tracking issue My watch was tracking my sleep just fine until 2 days ago. I checked my watch app on the my iPhone 13 Pro and everything was set up. The watch itself was fully charged right before sleep. But it reads NO DATA for the last 2 nights?

Apple Watch suddenly stopped tracking sleep data I recently purchased an Apple Watch SE 2, very happy with it, it has every function that I would want! Just two days ago it stopped tracking my sleep, and I didn't thinker with any settings, everything was already set by default and it tracked my sleep perfectly for two weeks straight. I did lots of troubleshooting fixes, restarted both iphone and the watch, checked every setting, sleep schedule is set normally, every single thing is set as it should be. I'm out of the options and I'm sad it doesn't work since I just got the device, it's brand new. nothing happened to it, I'm taking good care of my tech. Thank you for any suggestions!

Apple Watch not tracking sleep So my Apple Watch used to track my sleep every day and today I slept a little longer than I expected and it doesn’t show my sleep data and I keep refreshing it and it’s not showing up, even when I opened the app on my Apple Watch it popped up for a split second and disappeared again. Idk why that is
