Every time I join a multiplayer server or world, my skin automatically goes to a default skin. No matter which skin I choose, whether if it is a trusted skin from the marketplace, or downloaded skin, it will either turn into Steve or Alex. For example, let’s say I equip a skin like the Party Steve skin, and I log onto CubeCraft or Hive. That skin becomes either a default Steve or Alex skin.

The only Workaround is to uninstall Minecraft and reinstall it. After that, then classic skins are able to be used across multiplayer servers and worlds.

The thing I’ve observed with this issue is with worlds that take up a lot of storage. For example, let’s say you have a 430.9 MB world, along with many other miscellaneous worlds that make up around 5 worlds and you try to join a multiplayer server. Your skin renders back to default no matter which skin you use.

The only way to play with a classic skin on is without any worlds that take up a lot of storage.
