No one's custom skin shows up for me. Everyone is either Steve or Alex. On Minecraft Launcher it shows me what my skin is supposed to be and it says I currently have the skin but when I join a world it's always either Steve or Alex, it randomly switches between the two. Other people can see my skin but not me. It happens on survival and multiplayer worlds. I've looked into how to fix it but all the tutorials I've seen are for pocket edition. It's been happening for over a week now and it's getting really annoying.
