Error message "Download the Fitbit mobile app"

[donut2021]

So I’ve paired my charge 6 and Bluetooth is on but it’s just showing a sign on the watch saying ‘download the Fitbit mobile app’ which obviously I’ve already done. 
Can anyone help please 🙏

Open your Fitbit app and do a setup of toe Charge 6, which your device hasn't finished. 

See my other response to this question.

Hi there @donut2021! Welcome to the Fitbit Community! It's great to have you here!

@Rich_Laue Thanks for the help!

I suggest you try this too:

1. Update the Fitbit App.
2. Open the Fitbit app. On the Today tab, tap on Devices (Device icon, top left).
3. Go to your Settings, Bluetooth (Connected Settings), and "Forget" any Fitbit Trackers/SmartWatches if any are shown.
4. Restart your phone.
5. Open the Fitbit app and re-add the Tracker/SmartWatch (via the Devices icon, top left). How do I set up my Fitbit device? 
6. 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.
