The Deluxe Edition on Steam is buggy.

Hi, I bought the normal edition of Minecraft Dungeons and then purchased the Deluxe upgrade so that I could enjoy the upcoming DLCs and use my old skins from Dungeons I, which are now a Deluxe feature. However, for some reason, after purchasing the upgrade on Steam, the DLC skins, pets, and capes only work offline. When I try to use them online, I get an error message saying, “An error has occurred. Please try again later.” Could you please help me fix this issue?
