Thank You.
The issue I had was that ‘Health’s Data’ on my iPhone’s Health App was not data filling the Health App on my iPad. However it was syncing but then stopped. I had both apps set to sync the data via my devices. Rather strangely all other iCloud stuff like photos and notes was always updating and syncing yet health was not.
I am totally baffled.
I got fed up turned off sync on iPad waited a couple of hours and put it back on and since then it’s been ok.
However it was at least 3 days that it wasn’t syncing.
I am mystified
All I can think it that I was away from my home home wifi for a while using 4G with the iPad tethered to iPhone, if that affected sync, although it stopped before I went away from home and notes and photos synced as normal.
Many Thanks for reading
