I just successfully used MultiUploader so I'm not sure what issue you're seeing. Can you send that with details to Special:Contact/bug?

As for AWB, that's an independent feature (not managed by Fandom) and from what I understand we're working with them to make sure it can automatically use Fandom URLs. In the meantime, there's a custom option that will allow you to input Fandom URLs.
