"Instrument is currently marked as bad" when adding a Bank Account via IBAN
I am attempting to add a bank account to my PayPal account, in order for a webshop to accept my payment due to security measures, however when attempting to do so, I get greeted with this nondescript error message telling me that "Instrument is currently marked as bad".
I have already managed to transfer the actual funds to my PayPal account, but now it's seemingly blocking me from using them in this webshop due to the lack of a card?
Is there a way for either you or me to resolve this quickly? The payment is due pretty soon.
