Sleep tracking doesn’t work

[RoseRK]

My Fitbit Sense haven’t been displaying my sleep pattern, score and breathing fluctuations almost two weeks now. 
When I try to check it - the whole app freezes.

Same thing here but on a Charge 2!

My sleep hasn't been tracking either.  When it does it only picks up half the night, and does not seem accurate at all. Then in the morning it also has trouble syncing. I turn off the bluetooth and try to reconnect and it says "you need the fitbit app" after trying to connect multiple times it will finally work. I also noticed my battery is dieing super quick. A full charge only last a day or two. I bought this sense for Christmas so its not very old. Very disappointing.

Same here. My battery is super easily decreasing but my Sense is also quite new. I think 6 months now. I am FitBit user for 6 years and now I am quite disappointed.
