My rugged instinct is no logger tracking intensive minutes. This is my second Garmin instinct, the Garmin agent assured me I had rare defect. I returned it and bought another one, now one week later, since the last update this instinct no logger tracks intensive minutes. I did all the research and made sure my heart rate zones were correct, and still It will not track. Is there a perinate solution to this problem other than having to rest every week?
