Has anyone else got this problem. Have had my new ipad about two months. Everything working well but suddenly the double tapping procedure to bring up apps so they can be swiped up no longer works. The strange thing is that my old iPad which my husband is using is the same. He was using the iBooks app when it froze so I double tapped to bring the app page up so that it could be swiped up which in the past has always worked. When nothing happened I tried mine and it was the same. We both have iOS 10.3.1 as we have updated them. I then tried closing them both down holding home and closing down button. Again I still couldn't get the home button to produce the apps. Has anyone got any other ideas? I would be so grateful for any help.
