invalid SWIFT/BIC

Just tried to make a transfer in Euro to Barclays Bank Plc , shows me that bic/swift is invalid. Tried BARCGB22 and BARCGB22XXX and all codes from bank web. Do not know what is the problem with Revolut


I have the same issue (wrong BIC/Swift) when trying to save an account to RBOS in Guernsey before transfer. The bank can accept multiple currencies (codes not supported RBOSGGSP and RBOSGGSPXXX)

After reading all messages it looks to me like some kind of intentional avoiding accepting Revolut as a Destination by conventional banks - I do have the same issue with a german bank telling me that the BIC and IBAN is not valid which is nonsense.

so do we know what the solution is?
