Skin Not Allowed Error / Bedrock Realms

When entering realms I get an error that my skin (“Skin A”) is not permissible for multiplayer. I swap to “Skin B” and it works. The next day, I get the same message for “Skin B” and swap back to “Skin A” and it works. Basically need to change skin every day. And the pop-up won’t close after changing skins, I must close out of the game and re-enter.
