Kicks me off when on the world

When I go on Minecraft P.E I want to load onto my world I would get on be on there for 30 second (not ever that) I would be kicked off the whole app. I was so exited to see all the new features I wanted to got on as soon it was updated so I was so sad when I couldn't play Minecraft until the next update that might be 2 months from now. I not really sure if it is a bug however I am pretty sure it is.
