Addons won't work on realms

since 1.12.0 new Addons came out I can't get them to work on my realm. When ever I put them in the worlds Addons and then export it to realms it just removes all texture packs and Addons from the world. I've tried using different words on different devices but every time they instantly get removed even if the Addons items are placed in world or in your inventory.
