I've created an sandbox user in the bunq dev portal and when trying to login with the email and pin, the intent shown on the screenshot is showing.
If I go back, I'm just on the login screen again and when I click start verification, it just says there is a issue with the server.

Is this a (known) bug or how do I circumvent this and be able to log into the app?
Sorry for the german screen, I couldn't find a way to change language, but it says nothing important aart from "You're trying to login from a new device" at the top and well, the server issue on the toast notification.

Greetings :)
