The Marketplace is a unique section in the Minecraft Bedrock Edition where players can buy or obtain both premium and free third-party game features in the form of add-ons, worlds, skin packs, etc.

Generally, the WoW add-ons won’t work if those are corrupted or incompatible. Apart from faulty add-ons, the corrupted game interface or files of WoW can also make add-ons not work properly.
