Hello all, I've noticed that when using the dedicated workout app it will not have my heart rate taken until I manually cycle to the heart rate screen at at that point it will say measuring and then continue to show the heart rate for the remainder of the work out. But if I never go to the heart rate screen it seems like it will not have the heart rate available. I have to actually manually go to the heart rate screen for it to start taking heart rate. Does anyone have similar experience? What's your experience?
