Maybe you could try the next thing, go back in the app, tap your profile picture and then Edit in the right top. You will see "Legal name". Change this to your full first name + surname instead of first letter + surname. This is a new feature for users outside The Netherlands where that is the standard.
Now export a statement from the IBAN you would like to use, it will now show your full name and should suffice for verification in your current correspondence with PayPal. Maybe mention bunq is a full EU bank too and not just some payment service. ๐
Also when adding the bunq IBAN from the website did you change the country to NL, otherwise it won't accept the IBAN due to a different format?
