I have an apple watch 3. My BPM not reading
I have an apple watch 3. My BPM was reading fine in it before i added cellular plan two days ago...and reset watch. now it just cycles with no reading. How do I fix it. All settings are on that need to be on both the watch and my phone. I tried powering down patch and reboot by holding both buttons, tried switching wrists and loosening watch and moving lower. No luck.
