Hey Andreas, I figured out what's going on.

Because we use real people to transcribe the cards, we found that we were having trouble with accuracy when the cards are in languages other than English. As such, we flagged the app to countries that have English the primary language.

As we scale the app, we're going to enable more countries. But right now we wanted to make sure that we're providing the best possible experience, even if that means to a smaller base of users.

Very sorry for the inconvenience.
