Current Accounts and changing residency - what happens?

We’re looking at moving countries within Europe. I currently am registered with Revolut in The UK and am using the new GB current account feature to receive monies and pay regular bills. If we move to Europe a) how can we change addresses for billing purposes to our new european address, and b) would doing that affect our ability to use the GB current account as we’d no longer be UK residents?

ad. a) Visa in-app chat
as. b) yes, as long as you have permission to be based in GB. You don’t have to be there physically.
