I notice today that my Sleep and Heart Rate have not recorded for the last few days.
I see from the forum recommendations to power off/onn and this seems to resolve the issue - fingers crossed. However, I'd like to know if I did something to make this happen or is it a manufacturer issue that can only be resolved with watch power cycling to reset something.
Any suggestions what mght be the root cause?
eg would wearing the strap too loose or too tight cause this?
