Me and my friend is trying to play together but we can't join each other's worlds. It always says that the server is old when I try to join. I'm using a tablet on ios 12.3.1 and my friend is using an Xbox one. his Xbox says that it is on 1.11.4 and my tablet says 1.11.14 sometimes but others time (when it works) it says 1.11.4. how can it be going back and forth from 1.11.4 and 1.11.14?
