So, this morning I checked on my app store to see if MCPE was updated and it was! I spent a couple of minutes looking through the new settings menu and then decided to see what was new in-game. I made a new world called "Updates" and then it happened. The loading screen didn't go anywhere before it crashed and sent me to the home screen. I was so disappointed. So are my brothers.
Please fix this!
