App freezes in most recent iPads

Weve used this app for a couple of years on both iPhones and early-gen iPads without trouble, mostly for panda cam viewing. However, in the most recent iPad versions (both iPad Air 2 and Mini 4), the app freezes if you close out and try to re-enter. You need to do a "hard" close-out (double-click and swipe closed) to get it to work again. Please fix!
