@mtnsportsnutrition you can only mesure hr through one device a the time (belt or ohr), and you can’t change during an exercice.
Be sure to wear your strap belt defore launching exercice. Then the green heart showing HR sensor will have « little wings » (representing belt) if your belt is detected (it should be, it is prior to ohr). If ohr you have a simple heart.
You don’t need to unpin ohr in exercice settings (if you don’t wear your belt, Ohr will then work for mesurement)
So if you’ve recorded your exercice with your belt (I guess you’ve paired it properly with you watch), the HR data’s will be from you belt.
You’ll that explanation in the utilisation guide.
