hey guys .. I managed to save my progress .. even when I uninstall the game .. simply just copy all the files in the docments folder without the unity folder (the selected files in the photo incloded) .. then uninstalled it .. then install the game and start it .. choose a server .. and when the game starts .. close it .. go to the docments folder .. delete all the files without the unity folder .. then past the files copied from before .. start the game again .. and every thing i have before I uninstall the game is there
the thing is that i have jailbreak I don't know if that could happen on unjailbroken device
I tested this method on ios 9 and 10 both are jailbroken
