I use PlayerPrefs to save data from my game settings( sound On / Off, ect. ). When I play the game I can make changes to playerPrefs with no issue but when I quit it, my settings are lost and the next time I run my game they are not loaded. I tried PlayerPrefs.Save() when I exit the settings menu but this doesnt helped. Should I do some changes to App manifest in order to save my game data on disk or something else ?
