I have exported my game to scirra arcade to share my problem and to show it to more people because I can't resolve it.
the link to testing my game is this: scirra.com/arcade/adventure-games/fortress-34075
WHEN you click in the button of leaderboard (the button of the image that I have attached at this post) the sign in (with google) pop-up have a nagging error and the pop-up disappears immediately... help me please
the same thing happens into apk file
