I created a SEPA selling offer and it seems that it has been accepted by a Instant SEPA user, who is buying BTC. I suppose the taker will go to the bank and make a normal SEPA transfer but I wonder how is that possible. This is the message displayed:
This looks like a bug to me. I think SEPA and SEPA Instant payments are supposed to be treated like two different payment methods where you shouldn’t be able to take an offer with a wrong account.
