Last update, the pop-up had mentioned fixing skin visibility on multiplayer but i've been playing with friends on Realms for maybe two-three days now and our skins still hasn't shown to each other besides the default Steve and Alex.

The only custom skin i can see, besides mine, is the owner's.
I've yet to confirm if the bug of the other user's skin appears on me ,when we aren't playing on realms, is still there
