@MojangSupport help! Trying to play Minecraft beta on Xbox one. When I tried to load world says it cannot as it been saved on a newer version of Minecraft?! But only play on Xbox one and was only using it this morning #help :(

Was there a upgrade failure in your system?...have you tried updating the app manually?

Well the message implies that the version of Minecraft on Xbox one has gone to a previous one but it was working fine earlier.
