Really just an inconvenience, just wondering if anybody else's IPP has this same issue (or ?habit?). If I have more than about 5 open screens in the background, be they ooen apps or screens I have viewed in Safari, my IPP will freeze up. It always resumes once I double click Home Button and swipe up to close all open pages. So nothing I have wanted to have Apple look at but I have never experienced this before, I have had the ipad 2, 4 and iPad Air 2. I never cleared their open screens at all so its easy to get irritated at my froze up IPP at times. So just wondering about yours, who knows, maybe others just consider closing every few open screens as regular maintenance!
