Am I simply being ignorant or will the iPad air 2 not return you to your home page with the easy, and awesome 4 finger pinch action? My iPad 4th generation would always return me to my home page with this easy action, without having to use the home button. I can't return to my home page from email or Safari without using the home button. What am I doing wrong? I am not a "tech genius" but have always been able to return to my home page on my iPad 4 with the pinch action. Is there a problem with my new iPad air 2?
