@New-Red-Ermine-1082437737#289377 Hey there, Declan ๐
I see you've successfully cancelled the Joint Savings Account ๐ You now just need to open a new Savings account, which you can find out how to do, here!
In regards to the IBAN issue, 22 characters is the standard number of characters for an Irish IBAN, so it's perhaps a good idea to reach out to BOI and have them look into why you're not able to enter the full IBAN ๐
