the heart rate sensor works at random recently, but mostly just reads as "--". I've made sure it's higher up on my wrist but it also hasn't been logging my sleep appropriately anymore either. this just started a few days ago after working fine for many months. Heart rate sensor turns on when I enter the exercise app but then shuts off again. fyi, heart rate sensor is turned on in the settings. help!
Best Answerlike turn it off and on? or a factory reset?
because i've turned it off and on many times. doesn't do anything.
