Charge Anytime app not talking to Renault Zoe since Ohme stopped

Does anyone know how to get a 2020 Renault Zoe to talk to the charge anytime app. I've been happily using an Ohme epod via their app for 8 months but have now had to change to using the OVO app because OVO and Ohme have fallen out. My problem is that I cannot consistently get the OVO app and Renault to talk to each other. I plug the car in and it starts charging immediately and the OVO app says car not plugged in. I then go around the houses changing the Renault app to have a schedule, not have a schedule, have a schedule. I switch both apps off and sign back in a few more times then suddenly without explanation everything will work, the charging will stop, the OVO app will show a schedule and happy days. Bring back Ohme!
