Hi, I got a series 3 for about a year now and it has worked right up to today. I noticed that the heart rate monitor was not updated at all and my circuits stay at 0 no matter what I do.
Now on closer inspection, I realized that Apple Watch is not collecting any data. I tried to manually check the heart rate, but it just doesn't work and gave me old values (1 week old).
I tried to repair the clock like new, and checked all the settings. Any idea why this is the case?
