Due to my difficulty to fall a sleep, I always monitor my sleep with Fitbit Charge 2.
Last night a strange result appeared on my Charge 2.
I slept at 20:34 and woke up at 05:00 so I slept supposedly for 3:26 hrs + 5 hrs = 8:26 hrs.
But Charge 2 calculated as 6:54 hrs where are the ± 2 hrs gone?
Help me to correct those error. Thank you.
