For some reason my Nokia Lumia 1520 won't find an Xbox One SmartGlass App in the store, only Xbox 360. What could be the reason for this? I live in Hungary but it didn't work when I put my region to U.S.A. either. Please help
Well, the main reason is that it's not available in your country, but not working after changing region is weird. I personally switched mine to UK and found and downloaded it easy, perhaps try switching store region to UK?
