Okay, so when I tried to join someone's world, it kept failing to connect to the world. This was tried multiple times. However, when I take off the custom skin I was using and went with the default Steve skin, I was able to connect.

What was more confusing the person sending me invites was able to join my world on their xbox when I had my custom skin on, and they were even able to see it.

I know that my skin was "limited usage" (Only available on specific platforms) but if that was the case, wouldn't the skin been replaced with the Steve or Alex default skin when Xbox players connect to my world or when I try to connect to theirs?
