Amazfit Watch faces

Has anybody got their GTR to sync data over to Apple Health?

I use a Garmin for my running (because GTR has poor GPS) and that syncs steps/sleep but wear my GTR for rest of the time. It doesn’t even show up as an option in Health despite online instructions saying it does.

Zepp syncs my GTR data to IOS Health perfectly as far as I can see. However, in the IOS Health App there is no option to WRITE weight data to the Zepp App. I reported this to Amazfit.
