Hi there--I have deleted your other post which is a duplicate of this one. Please do not do this, since this is confusing for others to follow and help when there are multiple threads present. It is also against Forum Rules--Please review.
Regarding your issue--have you tried to force close the app? Give that a try and see if that helps. If not, best to restart the ipad by powering off.
Final step is to do a reset--power switch and home button pushed down at the same time. Give that a try and see if that helps.
