Has anyone managed to get their IBAN successfully changed yet? The system recognises my new IBAN and shows me a screen where it asks me to confirm my change. I do that (or so I think). The confirmation screen tells me "Banking update in progress, your changes should be reflected within 24 hours." and do I receive a ''App Store Banking Update' email a little while later. However, the screen that tells me the update is in progress also has a Save button. If I press that, I see an error message "Banking update in progress for bank account (***). So it can not be associated with US Dollar at this time." I've tried not pressing that too, but the final result is always the same: no change to my IBAN.
Is there some final confirmation step I'm unable to get past because of that extra Save button? If so, why do I get an email telling me a change has been made? I can't actually see my IBAN until many hours after receiving the email, and when I can see it again, it's still my old one!
I've had many emails back and forth with Apple Support and most recently they said "Our production team states there is nothing preventing you from updating your banking at this time. Please try again." I did try again, and I'm seeing the exact same behaviour: a screen which claims my change is being processed with what seems to be a redundant Save button that shows an error when I press it; an email which claims the change has been processed; and when I look at my account the following day, nothing has changed!
I think I'm going to have to try and delete my bank details and try and set up a new account...
