1. How to permanently turn off sleep tracking?
I don't wear it at sleep but it keeps tracking fault data. (If your watch doesn't smart enough to tell that I sleep or not, at least you should have option to turn it off)
2. How to delete fault sleep data????
unfortunately, you did not get answer after 6 months, meaning that disabling sleep tracking only is not possible...
I've been googling for hours, but i did not find any answer... you have to disable full activity tracking or let's your watch tracking wrong data
