During workouts my watch measures heart rate intermittently sometimes there is no data point for 20 minutes or longer. The watch fits snugly around my wrist and does not move around
Settings, Workout, turn off 'Fewer gps & heart rate readings'
iPhone, Watch app, My Watch tab, Workout, Fewer gps & heart rate settings
You should verify if the optical heart sensor is working during the workouts (the green light should work continuously). If that is working, then is not recording data.
Check also if in settings, not to be there a blocking set-up (although I don't think so).
I also remember a setting like the one you’re mentioning, but I can’t find it. Can you look in your AW, and let us know exactly if it’s (still) there (and where it is)?
I’m on watchOS 9.4.
Thanks. I don’t have it, even if I turn on Low power mode. Apple Watch SE 1:
Must be hardware dependent
