2021 A3 (8Y) Etron charging with intelligent Octopus Go

Is anybody having trouble charging with Octopus Go. I have been trying for 2 weeks to get my A3 to charge without success. I have at octopus's suggestion fitted a new 12v Battery (new battery was coded to the car) and that night full charge was successful. Since then small amount of charge or nothing. I have switched off the car timers as Octopus suggest to no avail. Interestingly after a failed charge one of the timers has changed to a random date in the future. Communication with the car does not seem to be a problem as Octopus are able to switch the charge off when I plug in outside the cheap rate hours (11.30.to 05.30) as normal.

I have switched off any charge settings in the my audi app - again at octopus suggestion

Octopus are suggesting that there may be a problem with the AUDI cloud servers.

Any input welcome

Thanks
