Phil Thanks! I now see how you got there: thru "Enter IBAN". I always enter the IBAN directly in the search field, so completely forgot about this option.
I checked what happened and basically IBANs among different countries can be pretty free form. So, to be on the safe side, we opted to just show a regular keyboard there. However, I think we can improve up on that. For example, German IBANs only have numbers after the country code: so it would make for German IBANs to default to the "numbers" part of the keyboard.
I'm gonna make sure this is fixed!
