No sleep data

[jstevens9455]

I wear my Fitbit Blaze every night but for the last three nights, it has not logged any sleep data at all. What needs to happen for my Blaze to resume collecting sleep data?

I have experienced some issues with my Fitbit Blaze. Last night I experienced what you're describing however when I rebooted my Fitbit the data appeared.  Previously for two nights could not generate sleep cycles.  It just told me how long I slept.  again I rebooted and the next night it worked

It's great to welcome you @jstevens9455 and @Carric thanks for stopping by.

As suggested by our friend, I also recommend restarting your tracker by doing the following:

1. Press and hold the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen. This should take less than 10 seconds.
2. Let go of the buttons.

Also, you can log out and log back in to your account.

I hope this helps, let me know the outcome.

I also have no sleep data. This feature has worked from the day it was introduced, but is unreliable sense your issue.  Yes I have restarted and logged  in and out.
