Ok so.. I have 2 friends, friend A and friend B. They can join each other in a world that they make BUT they can't join me. Also, i can't join them, the only way we play together is by going to LBSG servers.. Please fix this problem! My Gamer tag is EvolveMCPE and what I've also noticed is that it doesn't say Locating Server or anything like this, it's just Generating World.. And after 10seconds UNABLE TO CONNECT TO WORLD. It worked 1 time out of 100 which isn't good at all.
If you want me to reproduce it, i can record my screen and send you a link to view it on YouTube. I'll be glad to help you fix it if possible.

PLEASE don't take 1 or 3 months to reply.. Many people have this problem
