[Windows Central Question]

I have Spartan Strike installed on windows 10 PC brought from Windows Store.

I know that the location of save data is in appdata\local\packages but when I try to transfer my friends save game to my PC, the game gives error that the save game doesnot belong to my profile.

Does anyone know, how to transfer save game from one profile to another in windows store games? The process is very easy in other games like GTA V, where you just have to copy and paste the save files, but the same process is not working in Spartan strike.
