Custom Skins Cause All Players to Have the wrong skin

Whenever me and anyone else play together, if anyone has a classic custom skin, everyone playing will either have the same skin, or everyone will have someone else's. The only way to combat it is to have only one person with a classic custom skin and everone else have the new customizable ones. I do play on a galaxy S9, but it does appear on other devices from Nintendo Switch to kindle fires.
