Just tried to set up a direct debit for paying my American Express credit card (this one issued by BA) from my Monzo account. The DD failed to get set up (the error message at their end being “that account does not allow direct debits”). I understand other people had this problem in the past but it is apparently now resolved for them. I had no such issue with setting up other DD’s, only AmEx. Any ideas please? Anything I could be doing wrong?
