In the end I managed it by issuing a GDPR. Revolut's GDPR staff were able to finally shut the account, and send me the funds, so I got them back.
Perhaps if I describe the problem a bit more - I had the app, the app worked, the app was updated, and by being updated, needed a later version of Android (5.0). I was running 4.4, and so could no longer run the app, and as such lost access to my account.
