Minecraft keeps Teleporting Me!

Minecraft has been messed up since that new update. It started with it loading all the way up to the generating world part and then it would crash. I fixed that by deleting Minecraft and restarting iPad and redownloading it. It was working fine but then on a world that I just created it would keep teleporting you back to spawn point. No matter where I went. I really don’t want to delete Minecraft again because I can’t login to Microsoft so I can’t save my worlds.
