Inspire 3 won't track my sleep data

[Sarsfields]

New to Fitbit but find my sleep score not being routinely scores with message saying unable to detect heart rate.  Keep watch on all the time so not related to positioning on wrist

Hi there, @Sarsfields. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Inspire 3. 

Keep in mind that you must see sleep stages in order to see your sleep score information. Please swipe left on the Sleep Score graph, here you can see information about your weekly sleep average and sleep duration. To get more detailed information, see What's sleep score in the Fitbit app?

With that in mind, I recommend considering the following in order to get 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 with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

I’ve been having the same problem.  Fitbit replaced my device and I still have the problem intermittently.  And now my Fitbit won’t sync!

I do the re syncs as advised every time, leave it on all the time in the same position, sleep more than 3hrs etc. etc. and still no explanation as to how it works one night and not the next, very frustrating 😞!
