I have a problem with my minecraft for xbox one.

I can't access my friends' multiplayer worlds because during the upload I get this error message: '' impossible to join the world ''.

my friends can't get into my worlds.

I had installed the minecraft beta 1.15, then I removed it, now I have the latest version of the game (the new 1.16.1 for xbox one)    same as that of my friends.

why am I incompatible?

please I need a quick answer, I need the problem I have to be eliminated. I have had this problem for about a year
