I have Apple Watch series 0 and I noticed it doesn't monitor my heart rate. If I start exercise app or heart rate app watch reads heart rate no problem. However when I open my health app it only shows heart rate readings from when I manually made my watch read my pulse. It doesn't show heart rate readings through out the day. I have both heart rate and fitness tracking enabled. I'm running latest 3.1 and have tried unparing my watch. Anyone experienced this problem or know of a sultion?
