I deposited yesterday via Visa (First Direct debit). Got a OTP from the bank, submitted it and then received a fairly ugly error message that bypassed all the site style settings that essentially said 'failed. contact your CSR'.
Clicked OK and the deposit had gone through.
Trying to work out what the villain had after a hand could be improved, apart from that all good.
This is a pretty annoying known issue, but they are working on getting it resolved ASAP.
Almost a week old now. How time flies...
