Apple watch not picking up heart rate during run
I'm not exactly sure when this started, but during my runs, my watch is no longer picking up my heart rate. I've tried going to the watch on the app and choosing the heart rate to show, but for some reason, it is "grayed out" and won't let me add it. Is anybody else having this problem? I know in the past people had this problem with power saving mode being off, but I've checked and mine is still on. Thank you!
