Sleep showing wake up time after current time

[TondoS]

Fitbit sometimes "calculates" wrong wake up time - see screenshots attached - for example today, I woke up at 05:30. I went to bathroom and then, at 05:39 I looked at the Sleep. Fitbit claims that I slept till 06:03.

Hello @TondoS 

This article explains how Fitbits track sleep (<-- click link).

Like you, I've experienced having my Fitbit track the wrong sleep or wake time. When that happens, I correct the time in the Fitbit app. If you would like instructions on how to edit your sleep time in the Fitbit app, click on the link above.
