Greetings, So I'm working on porting our game to Windows Phone 8, got the port working fine. I'm using FullSerializer (JSON) to serialize my data and a get a string that I store in PlayerPrefs. When I save and quit the game, and come back again, everything's loaded back just fine. But, every time I make a new build from Unity and run it, the saved data is gone. I'm just worried because how are users supposed to update to a new version of the game then? Why is the data lost if it's being saved to PlayerPrefs? Is PlayerPrefs local to each app on the phone and not global? i.e. when you uninstall something anything related to it is now gone? Any help or advice is appreciated. Thanks.
