I know this is already an addressed problem, but idk if it was known that it is known that it also affects the latest version.

Anyways, on local two player mobile, the moment I join his server or vise versa, our skins switch. This happens to the both of us, and so our paperdoll, inventory third person, third person, etc.. we are wearing the other's skin. But to each other, we are wearing our respective skins, but all the above still applies. So to each other, we are wearing the right skins, but on our screens, we are wearing the other's skin.
My friend also uses iOS
