Problem with Apple Pay

Hello guys!
I opened a Monzo account, passed all ID checks. I got a message that I will be able to instantly add Monzo card to Apple Pay. I tried but i couldn’t add card.
What have I done wrong? Thanks!

Hi Uyen,

Welcome to the community.

Would you be able to give us a bit more detail? Is there an error message? What did you do/try, what’s happened afterwards. What phone/OS version do you have?
