Sleep score has changed for the worse since iOS upgrade

Since the recent iOS upgrade my Sleep ratings have gotten significantly worse and my REM has almost disappeared in the Apple sleep app. Anyone else?

iPhone 14 Plus, iOS 26

Did you also update WatchOS to 26.2?

I find watch upgrades difficult because it requires the Watch be on the charger and charged at least 40 percent AND the phone be nearby the whole time.

I wear an Apple Watch series 10 (GPS) 46 mm on my left wrist.

I do have a sleep focus set for 10PM to 9 AM daily.

No issues.

I updated the iphone prior to updating the watch. My watch is never at 40% battery level unless I am using it in a sports event.
