Charge 2 sleep graph has changed

[nickri]

My sleep display used to show light sleep, REM, deep sleep etc. It changed 2 days ago now it shows how long i took to fall asleep and other stuff, I can't see how to change it back,

@nickri It's great to see that you've visited the Fitbit Community! Sorry to hear that you aren't seeing your normal sleep information. These are sleep stages and you may not get them for the following reasons:

• 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.

You can also restart your tracker.

Let me know how it goes!
