I enjoy playing net play though LAN on minecraft, however I have been having some skin issues. You see when I play my skin shows up as my skin on my screen. And my friends have their skin on their screen. And when I see them I see their skin, but when they see me they see the default skin. We all have an internet connection, and on our computers our skins are showing up normal. The issue is that they see me as the default skin instead of the normal skin.
Well it might just be that your friends are on a different version than you. . But some servers have something where everyone looks like STEVES so it might just be the server other than that try changing your version along with your friends and maybe try another server.
We are all running the windows version.
