Crash when i play and record.

That was back with IOS 9. and game version 1.1 Hi, when i play and record my game in Reflector 2 (i play in Ipad 4 with retina display) my minecraft pe crash. 10 minutes crash game 2-3 times. I have tried to delete the game and downloaded it again in app store. It does not help me. When this is over I will be able to play and record video in the game I bought? on windows I can't remove, because I have no games on windows 10.
