Unfortunately that did not work. The skins were created in the Minecraft Custom Character creator so they’re technically trusted. My friend is playing on a Nintendo Switch so I don’t know if that may be a problem on his end.

Thank you for your report!

In Settings > Profile, is "Only Allow Trusted Skins" enabled? If so, does disabling it fix the issue?
