Since upgrade to 2.0 heartrate are no longer logged in Health app. Heartrate Glance display last measure to 1 day ago and manual measurement ends with a failure. Green sensor no longer activates.
HeartRate no longer working
Sorry I missed the end of my post. Does anybody have any cue on how to fix ?
Try a full reboot of your watch. Possibly a reset and re-pair it.
Mine didn't record heartrate in the health app at first, but now is working fine.
