Well well well at least the review guy did try much harder this time doing everything above and still i get failed reviews using [HR] i suspect from the description fails on square watch still best to exclude that device either with latest updates
You can add the below description.
*** The watch must be worn on the wrist for Health and Sports data to work
*** Oppo and square watch models are not supported at the moment!
Did you describe it as a Heart Rate Monitor, or was that their words?
