@Tim JohnDo @WJanson I think the confusion is either because they gave the wrong info, or because they themselves keep confusing the Travel Card with the membership rather than the card type. :P
In the support chat right now, another bunq employee confirmed that the Travel Card cannot be linked to any IBAN but rather has its own IBAN that can be used to top it off. To prevent any confusion: I have repeated the question to explicitly note that I'm talking about a Travel Card card under Premium, and asked if I can't link it to any of my (up to) 25 IBAN's with Premium. The answer is: no, you can't. In fact: "You cant link Travelcards to IBAN account, if you need money on the travel card you can top it up from one of your other accounts and money appears instantly"
This is the second bunq support employee that tells me it's impossible, so now I'm really confused as Tim says he can currently actually link it to any account he wants. So what's going on here? :P Both bunq employees are wrong? :P
I know you guys often know a lot, but when multiple bunq employees start telling me, even after making very clear I'm talking about a Travel Card under Premium: the situation becomes doubtful and I'm not sure who to believe.
