Charge 4 not syncing

[CDSUK]

My charge 4 has stopped syncing datz related to sleep, breathing rate and oxygen saturation. Have reset and checked all settings with no solution.  Any thoughts? Thanks

Fitbit must have a glitch.  My charge 4 is only capturing ½my sleep and won't let me edit to the correct time.

Hi there! @CDSUK and @Dydedo welcome to the Fitbit Community! It's nice to have you here.

Thank you so much for informing us about this situation.

Our team has been looking for a solution and has recently launched a new version of the Fitbit app. 

Please try to update your Fitbit app to the 4.28.3 version. If it doesn't work, please restart your phone and try the steps of set up as new device again:

1. Update the Fitbit App to 4.28.3
2. Open the Fitbit app. On the Today tab, tap on Devices (Device icon, top left).
3. Delete any connected Fitbit Trackers/SmartWatches, if any are shown.
4. Go to Android Settings, Bluetooth (Connected Settings), and "Forget" any Fitbit Trackers/SmartWatches if any are shown.
5. Restart your phone.
6. Open the Fitbit app and re-add the Tracker/SmartWatch (via the Devices icon, top left). How do I set up my Fitbit device? 
7. From the Fitbit app, Today tab, Tap or Hold near to the top of the screen and then drag down to perform a manual sync.

I've tried your suggestion step by step and the app briefly showed my actual steps in the 9000s then the display reverted to the wrong number of steps in the 4000s. I have another app on my phone that tracks steps so I have a pretty good idea of what the total should be today. Any help or updates appreciated!
