Thank you for your request.
The language of the app automatically adapts to the language of the device (German, French, Italian, English).
If the device is set to a different language, English is displayed by default (for new installations). If the device is switched to a different language after the app installation, the app remains set to the last displayed language. That’s why I recommend you to select English language first and then switch to your preferred language (English will be displayed in the app then).
For any other questions about the mobile app, please contact the Ticketshop (firstname.lastname@example.org).
