Two things u can try, uninstalling it, then reinstall it again.Originally Posted by skiax
Do a soft reset. While iPad is on, hold slepp and home button down at the same time for 5-10 secs. The iPad should reboot to the apple logo screen and hopefully the issue went away. Sometimes when apps start acting up or non responsive, the reset method will get things back working right.
Also did u do what DontUnderstandMyIpad said?
