The game keeps crashing I feel because I have an iPad 8 gen and minecraft is not optimised for iPad 8 yet please do fix it

Minecraft not optimised for iPad 8th gen or the processor maybe but whatever is the problem causing it my game keeps crashing and I think this is because it is not optimised for iPad 8th gen because it works fine on my friend’s iPad 5th gen. Please fix the issue. 
Thanks
