Sleep Stages stopped

[Steverino]

I have a Charge 2 and have had sleep Stages for months but last night it stopped and I didn't have them.

Fitbit suggest there are a few reasons this can happen:

"WHY DON'T I SEE SLEEP STAGES TODAY?

There are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages:

• If you slept in a position that prevented your tracker from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your tracker higher on your wrist (about 2-3 finger widths above your wrist bone). The band should feel secure but not too tight.
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your tracker to bed). For more information on automatic sleep tracking, see How do I track my sleep?
• If you slept for less than 3 hours.
• If your tracker’s battery is critically low."

Same with me. In the app no data at all appears today about last night sleep. I tried to manually add my sleep time but the app responded that there already is a sleep record for that night. But is doesn't show in the app. Strange.
