I'm finding that my Garmin HRM-Run, the red one, doesn't auto connect when I start an activity.
Other sensors are fine, power, speed etc it's just the HRM that has the problem. It has a new battery and connects fine on the fenix 6x.
If I go into the sensor menu and connect manually it then fine for the entire ride - not a total showstopper but it's annoying
any thoughts ?
