Blaze isn't providing sleep stages information

[EnglishTeacher]

I have only gotten simplified sleep analogies for over 2 weeks. If I set up my Blaze as a new device, will I lose all of my history. I don’t lose that!

Thanks for your help.

Hey @EnglishTeacher, it's great to see you around.

If you are having issues with the sleep stages feature, 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 device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device 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 device 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 device’s battery is critically low.

Let me know the outcome.
