I am playing Robot Unicorn Attack 2 (don't laugh) on my iPhone but when I am home I like to play it on the larger screen of my iPad. I dont play alot of games on both devices usually sticking to the iPad for the most part so dont know how simple this is. The iPad does not remember my progress on iPhone. I am logged into gamecenter on both devices. Anything I am doing wrong? I looked in the games settings in "Settings" and I see nothing obvious.
