Brand new iPad Air 2, downloaded mine craft PE. When app is opened, sometimes will play for awhile (up to an hour at times) but the majority of the time it crashes (suddenly returns to iPad menu) quickly - instantly, within seconds, or a couple of minutes. I also purchased an iPad mini 4 and do not see this issue. I contacted apple and they suspected it may be because of the larger size of the iPad Air and the increased graphics associated with it. We have tried to uninstall the app and reload, with no success in fixing the issue. We also make sure no other apps are open.
