Charge 6 stuck saying download App

[John.uk]

My Charge 6 stopped recording REM & Deep sleep two weeks ago.  Following a suggestion on a Board, I deleted the Charge 6 in the App and then tried to reinstall it.  However, I am not stuck with the Charge 6 saying "Download the App". I deleted and re-downloaded the App but it is still stuck.  

On trying to add the Charge 6, it finds it but says Lost Blue tooth Pairing.  The Charge 6 just keeps saying "Download the App" but will not give a pairing code.

I have tried rebooting on the charger button (3 time with a second delay) but the Charge 6 still says "Download the App".
