Hi Grandy, sometimes the usual "immediate fixes, helps to sort things out on your iPad. Not sure what you have done yet, but try the following below...
Have you tried to do the following?
1. Force the app to close?
2. Try to restart your iPad?
3. Try to do a reset?
You can try this in order, if an app becomes misbehaves...
Force the app to close down*by pushing the home button twice or by doing a 4-finger swipe to bring up your multi-task bar. This will show all the apps that you have visited. Press the app, until it begins to shake. Close out the apps by pressing the red circle in each app. It will only quit the app and not delete. Than try to re-open the app and test out.
If that doesn't work, restart the iPad by pressing the power switch down to power off.
Third is to do a reset by holding the power switch and home button together until you see the apple logo. Hope that helps!
