Bosch Nyon 2021 factory reset

Hi all

Any one done a factory reset on the new Bosch Nyon display ?, reason asking folks i did one and now it will not connect to the motor , i am able to scroll across all the pages but no up and down speed settings , their is no battery charge symbol showing which again tells me its not connected , tried resetting dual batteries , that never worked, and i do have the latest update installed for the display.

Charged the 2x batteries on the bike , no charge symbol showed , it will charge the display when charging, but not while it is sat on the bike switched on.

No error messages .

Any suggestions ?

Cheers all !
