Won't stay in English – Museo Duomo Review

I downloaded the app at our hotel and tested it, and it all seemed to work fine. But upon arrival at the museum, all the art descriptions switched to Italian, and there was no way to change a setting to change it back to English. Then when I arrived back at the hotel, it switched itself back to English. What kind of app decides what language you can see on its own? Very odd. It didn't seem to be based on location services, so presumably you need wifi or data for it to be in English?
