Apple Health shows inaccurate time in bed
I am facing a problem with my sleep data. I use Mi Fit fitness tracker and it works just fine - sleep is very accurate. But when I open mu Apple Health App, it shows 17-18 hour of bedtime in addition to asleep time, which is not correct. It looks like Apple Health makes some unnesary magic after it gets data from Mi Fit.
I wouldn't bother, but one of the apps I use to analyse my sleep, etc, gets data from Apple Health and provides me with inaccurate values.
Does anyone else encounter this, and what is the solution?
