Hi. I've tried to join my friends servers but is says "unable to join world" so I told my friend try joining my world and it said the same thing for them aswell I've made sure we have the same wifi connection and same minecraft version but nothing seems to work and I have had this problem with minecraft for quite awhile I have tried to find harmless hacks for it but nothing seems to work this has lead me to not play minecraft for quite awhile but I really enjoy minecraft and I want to start playing again. Please help me resolve this issue.
