Multiplayer is as buggy as it was, once again, in previous versions before 1.11. I can't connect to anyone's world and nobody could get into my world through xbox live. This bug has been occuring as if it has a cycle every some number of updates and it starts to happen. This just seems very broken especially Multiplayer is something which's like the main thing of MCPE or just Minecraft as whole as it ruins experiences. Please drop a hotfix or just some immediate updates in 1.12 rather than waiting the whole month or 2 just for 1.13 to be released with its own bugs.
