If you are having problems with your iPad turn the app off. (double click home, then press and hold one of the apps and then press the minus button) If that still doesn’t work then turn your iPad all the way off. To turn your iPad all the way off you press and hold the off button until you are able to slide an arrow. You slide the arrow and the iPad will turn off. This will take about a minute. Them you keep pressing the off button until there is an apple in the middle of the screen. Your iPad is now turning on and when it turns all the way on then you go back to the problem you were having and retry to do whatever you were doing. If this doesn’t work then go to an Apple store and get it fixed.
