@Glos Guy yes, I know the transfer process (done it plenty of times via DVLA site on non mob cars). I was just asking if the various databases MoB and their partners use update swiftly. For example if you get a puncture two weeks after putting your plate on, go into KF saying your MoB car has a puncture and they put the (personal) plate in the system. Was wondering if you, or anyone else, had ever encountered any issues.
