Whenever trying to join a friend's who lives countrys away from me(to be more exact I live in morocco and he lives in South Africa) it would always end with unable to Join this world screen even tho we both have good wifis, there's one possibility that I can think of for now at least and I think it's server hosting problem, since there was this one time he's friend from another country was the world's owner and we were both able to join. Thanks for your time
