Apple Watch Stopped Tracking all Activity and Heart Rate

Hi There,

A few days ago, my watch stopped tracking all activities and heart rate. I have tried all activities to try to correct. I unpaired/paired with “new”, all toggles are on (as they were before), recalibrated activity and went for a 20 min walk/run, check privacy toggles, etc. I will note that the “tracking activity” is on but greyed out, on my watch.

Appreciate if you can suggest anything else that I may have missed, to correct this issue.

Thanks

Peter
