I had put my complaint in to Motability last Saturday at 11.30pm, and on Monday morning there was a change on the RAC App, neither of the cars, old or new is present, as when you click on the tab for your vehicle, its an error msg saying. ‘Due to a technical hitch, please try again later”. As I thought, Motability and the RAC have not ironed out the bugs between their systems. I guess Motability will have to go back to manually inputting the vehicle changes on the RAC Portal if it was something that could be done by the help desk bod then they would have done it there and then.
Every chance there is some cached RAC App data on your phone which needs clearing. Sometimes deleting the App and reinstalling it will clear the cache (but not always!).
