I'm having the same problem. I've amended the ESA under Employer Details and it has a green compliancy tick. But the portal still rejects the transaction and keeps showing the old ESA under Issues. I've received the same Contribution Error Notification email twice but there's nothing I can do.
It looks like the only solution is for the payment to be refunded so I can reverse the transaction and re-process it in Account Edge.
How can I get a refund?
