Fitness app continually losing data / Health in iCloud is Turned off?

I have an iPhone 11, with iOS 16.3

The fitness app keeps losing data until I restart the iPhone.

I am using a Withings Health Mate app data from Withings watch for activity tracking and their BP monitor and smart scales. Also running the MyFitnessPal app for calorie tracking.

All data seems to sync for a while, but eventually at multiple points during the day when I look at the Fitness app to monitor my progress the date for that day and all previous days do not show in the app. The only way to get it back seems to be to shut down the iPhone and restart it. The Withings app shows connected to the Apple Health app ok and visa versa, but when the data goes missing the Apple Health app shows Sharing Apps a spinning wheel, as if disconnected from the Withings App.

I Also just noted that the Health app under sharing is now showing "Health in iCloud is turned off" but when I go to iCloud settings it is turned on?
