When I ride with my Edge 830 the heart rate data for the ride is correctly recorded from the heart rate strap for the ride on the 830 and in the ride activity history. The heart rate captured in the Garmin Connect app is recorded from the 745 wrist sensor which is always significantly lower and less responsive than the strap for aerobic activity. As a workaround I can start a treadmill run while I'm riding and then stop and delete it and that will get the correct heart data from the strap. I would like to be able to have the strap automatically be the active device when connected.
