Szymon me card is delivered but im waiting 3 weeks more and still nothing.
The date in the app is a rough estimate. The cards are sent via normal postal mail without tracking (except Metal Card). If the address is correct, it will most likely arrive at your place at some point. Because the cards are sent from The Netherlands, depending on where you live, it may be faster or take a little bit longer for the card to arrive.
If you think your card has been lost in the mail, you can look at this topic for more info: https://together.bunq.com/d/711 Pretty much all cards arrive eventually, though.
