I’ve seen sepa transfers from my AIB a/c to my N26 a/c vary widely in the time they take, and second next working day wouldn’t be unusual. Making the transfer after 5pm on Friday is probably the worst possible time given the way AIB operate with transaction cutoffs, short working days (due to Covid apparantly), poets day, 3 day weekend etc. If the money hasn’t turned up by 11am tomorrow phone AIB and notify them that the transfer failed and ask them to investigate. Last time I did this and kicked up a fuss the money magically appeared in my N26 account 45 mins later marked “priority”.It was after 5pm on the Friday.
Out of curiosity, I opened the payment log in my AIB app and pulled up the details of a sepa transfer to N26. I had no difficulty screenshotting it. Phone is an iPhone 13 with iOS 17.
