Device not tracking Sleep Stages

[The-Panda-Me]

My app said it needed to update, so I let it. For the first 3 to 4 days after that, I got a sleep score and an actual sleep chart that told me how long I spend in each zone. But that disappeared, and I am left with the basic track that doesn't tell you much. I want my good tracker back. How do I do that?

Hi @The-Panda-Me, welcome to the Community Forums!

Thanks for bringing this to my attention and the details that were shared in your post. There are a few scenarios where you might see your sleep pattern (which shows your time asleep, restless, and awake) instead of sleep stages, find them as follows:

• 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 you can  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 if you have any additional questions.
