some times when i try to join my friends world it will say connecting to multiplayer game and then say unable to connect this could go on for hours sometimes days.

It has come to my attention that the amount of bugs in multiplayer and so far i see nothing being done about it for one sometimes the local servers cannot be joined even though i see other people using the servers two sometimes when i attempt to rejoin my friends world i get a message saying connecting to multiplayer server and then says unable to connect this is repeated for sometimes hours sometimes minutes sometimes day and i would like if this issue would be resolved as i enjoy playing with my friends and this issue is causing us to not want to play mine craft to much
