Everytime I'm in a game it doesn't show my profile image and my friends can't see my skin

The issue with the profile picture not showing is tracked at MCPE-170710. For the skin issue, do your friends have the "Only Allow Trusted Skins" option enabled in Settings > General? If so, are they able to see your skin if they disable that option?
