Hi, I just downloaded Adventure Town on my new tablet and was trying to sign in to Google+ to get my saved game data from my other device. The forum I read before said you could do this after completing the tutorial. I did, but it still won't let me sign in. It gives me a darkened screen like its about to pull up a login screen or something, then goes back to normal after a couple second, still not logged in. Anyone have any advise on how to fix this?
