Sleep stages not showing

[Beccilou]

I've recently got myself a charge 2 we high tracked the sleep stages on the first night but hasn't ever since and is only showing the basic sleep information. I have already tried the solutions provided on the app such as wearing it 2-3 fingers width from the wrist bone and making sure it isn't too tight/loose. Has anybody got any other suggestions?

Look at your daily heart rate graph on the fitbit.com dashboard to see if you are getting uninterrupted heart rate readings throughout the night.

Here are the other suggestions, which you might have already tried:

Why don't I see sleep stages today?

Just got my 3rd Charge 3 since Christmas 2018!  Complained that the 1st one would only show basic sleep details, no matter what I tried.  Fitbit sent me a new one.  Same results!  Then, Charge 3 #2 started losing the top of the time display.  Just received #3 and anxious to see if I will get detailed sleep info for the very first time since Christmas with 3 different devices.  My hopes are high, but my expectations are low, after the lack of help I got when calling in for assistance.  They made me send the first one back, before they would send the second one, but this time, they simply sent a whole new Charge 3!  Makes me wonder if a new model is on the horizon to correct problems they know exist with the Charge 3?  Has anyone out there achieved detailed sleep results with their Charge 3?  If so, what is your secret?  I have tried both wrists, high and low, tight and loose, and even wearing on the inside of the wrist, with nothing but basic sleep details.

I have a Versa and up until one month ago it showed my different sleep stages. Now for the last month it just shows the basics, no sleep stages (deep, REM, etc). I have restarted it, cleaned the back sensors, slept with it on the other wrist and nothing seems to work. Any suggestions?
