I've started getting a problem there as soon as I go to bed (look at sleep tracking), my clock starts logging exercise minutes and doing this literally all night until I wake up. I wake up to 400+ "exercise" minutes and thousands of calories "burned" in the activity app. Have fun. My heart rate behaves 100% normally, so I have no idea what triggers it to detect exercise.
I reset the exercise / exercise calibration data and recalibrated with an outdoor trip (rebooted both phone and watch a few times this past week as well). This solved it for 2-3 days, but then it happened again last night …
Before I unpair / repair (I do not like to do this …), some other suggestions to try I do not have Thinking of?
