Just keeps crashing no matter what

The game crashes. If i attempt to play this game at any time it crashes. Every time you do an update it gets worse and worse. The game has not operated properly for many updates.
Attempted user fixes:
Dump entire iPad mini reload iOS and only install fresh new minecraft, still won't work.

I can't include a screen shot of the error, just picture the game freezing and crashing and me being aggravated.

Can you please create a way to revert back to a Minecraft version that won't crash?

I can't see myself putting any money towards this game until it starts working at a professional level.
