It looks like my heart rate stopped tracking about 8.00pm last night. Nothing else tracked last night. I could not got the touchscreen to wake up so put the watch on charge, the button on the left did not seem to work. I reset the watch which bought back all of yesterdays steps for today , but till no sleep or heart rate. I can now get the time on screen but when I scroll to look at tracking..etc . Every so often it keeps buzzing and showing icons notifications and screen something greyed out (as if it cold not retrieve data).
I can get it to sync steps and flights now (albeit yesterdays plus todays)
I have tried resetting and changing the clock to see if that updates the heart rate .
Is there a sensor for tracking the heart rate that could be playing up?
