okay good to know.
So, if I had changed the language of my phone to french, the card would had been also french, and the language query would not have been asked.
Unfortunately my french is to bad for using my phone with it, but good enough for reading the screen and buttons on a payment terminal. (oui aucun annuler)
Maybe, changing the card language based on location, or changing it independently from phone language could be a nice feature? Maybe in the cards menu by allowed countries. Something like Cardlanguage (Same as Phone/ locationbased/select by country) or so. Could be interesting for FR GB IT ES and many more.
Maybe you could write it on the wishlist?
