For the past two days, my watch has not been monitoring my heart rate during non-activity times. I am going to go for a run later today to see if it will work for activities. I have looked up ways to troubleshoot this problem, but none of the solutions that have worked for other people seem to work for me. I am wondering if anyone else is having troubles with their heart rate sensor since the sensor hub 3.20 update? My green light isn't even turned on.
