Hello,
Just to check, did you answer the multiplayer related questions with these answers? (“Fortnite-Wide Standards for Interactive Elements” section of that doc)
There’s also a community created tutorial to watch.
If you think that’s all good to go, I’d change up the feedback contact you mentioned. (Maybe it violates rule 1.2? “You may include your social media handles/channels as long as they don’t include a URL or QR code or a request for direct or private messages”)
