randomly stops measuring HR. And I can’t get it to start doing it sgain? New to Garmin in an experimental changeover from Fitbit - will be going back if this keeps happening ?
I suspect you're talking about the built in ohr. How are you seeing it stop? If you peek under the back, are the green leds still on? Are you running a CIQ watchface and only seeing it update every minute? (that's normal for some). In settings, is WHR "on"
