When I go into the dressing room and customise my character using the Character Creator, the customisations I applied doesn't show up. If I try and edit, it just stays as Steve. However my customisations online (marketplace and imported skins), works fine.

Also when playing with friends, I can see them as Steve, but they can see there customisations. I've seen this with my friend who uses their phone but another friend who plays on his PS4 doesn't have this issue, and can see my online customised skin, but not my Minecraft customized skin.
