This glitch only happen on servers or any world that have online players in general, it cause all the entity (except the mobs) to turn into steve after a few moments of joining and you will stuck into the skin (or any server costumes) that you wearing even when you change it only from your vision, the only way to fix it is to leave and rejoin but it still going to happen again and again whatever you do, it's really annoying to me and to everyone as I can see from others chat, it mostly happen to mobile devices and by number of players so please fix as soon as possible.
