The latest version of software and firmware release of March 2020 has a new bug in the way it calculates sleep. It appears sleep time starting time is shifted about 2 hours resulting in night sleep much shorter than it used to be in the past.
Example: I went to sleep at about 12:15 am and woke up at 6:45 am. Ionic synced to my phone about 3:45 hours sleep. It is apparent no sleep was recorded in the graph until about 2:45 am.
Fitbit, please don’t rush new software or hardware releases unless tested properly. I have seen plenty of issues in past releases.
thank you.
