I have found on the store "Nokia Pro Cam" app and I want to install it but it says "This app is not available for your device. Tap here for more info.", "This might be because your phone software needs to be updated, the app is exclusive to a different mobile provider, or the app is not available in your country/region". I have Nokia Lumia 820 and my setting for Phone language is: Croatian, Country/Region: Croatia, Regional format: Croatia. Do I need to change those settings in order to get that app? Btw, I don't yet have Amber on my phone.
