Hi,
I noticed this issue with my vivosmart and with my newly Fenix 3 HR. The app display a complete wrong sleeping records outside the normal sleeping time. As a matter of fact it doesn't track any sleep if I go to bed after the wake-up time.
I usually go to bed by 11:30pm and wake-up by 5:00am and that what I used in the app. couple of weeks ago I had to work on a project with a different region which made me go to bed at 7:00am, the app didn't record any sleep I thought the issue was from my vivosmart. When I got the Fenix few days ago it happened to be during the weekend when i go to bed on time, but once the week started I noticed that the same issue happened. I tried to change the sleep hours in the app to be from 8:00pm to 8:00am, but then the app started to show 9:30 hours sleep every day without any log and despite how many hours I slept.
Any help or advice?
