Received the same message today (Friday), but nothing was in my mailbox .
Also today (Saturday) no card in my mailbox. In the app under the card image there is a link now, it says ‘Ik heb mijn kaart niet ontvangen’, in English that is ‘I did not receive my card’. But when I click the link nothing happens. Anybody has a clue what should have happened? Should a chat with support have opened?
