Jeroen 🏳️🌈 Solved via Sofort using another bank account.
But just to make clear: signed up as Free (not Premium), the first top up needed to activate the travel card is only Ideal, Sofort and Credit card with fees. There is no Bank Transfer option. There is also no “add money” button and no way to see the Bunq IBAN. The top up menu is accessible only from the “request card” wizard and contains no Bank Transfer.
After first top up you get the Add Money button in main screen, with Bank Transfer and iban info.
So, not a big deal, you might spend 0,5% fee at first credit card top up, but only the first one.
Maybe it’s not a bug, it’s a security issue, or maybe it is..
