Troubleshooting Apple Heath:

See fi the default app has changed.

1. Start Here: Use the Health app on your iPhone or iPad - Apple Support
2. Scroll to: Choose which apps share information with Health

My iPhone has not recorded sleep patterns since September 17 2024 on my iPhone 12 Pro iOS 18.2. I looked at About iOS 18 Updates - Apple Support (IN) and did not find any change with respect to 'Sleep'.

I have deleted the sleep schedule and added a schedule in the Health app. Will check it tomorrow and revert.

Yes, there has been no sleep data since 17th Sep 2024 even after deleting and re-scheduling Sleep Schedule.
