Why does the Fortnite launch say “failed to download supervised settings “

Hi Kelly! My name is Darhyl and I’d be more than happy to help you with your query.

I'm sorry you are experiencing this with your Fortnite game. No worries, let me help you sort this out.

It's important to note that this is a public user-to-user community forum, and none of us here work for Microsoft.

I just want to confirm, by resetting your console, do you mean factory reset keep my games and apps?

Since you have already cleared your alternate Mac address as well as launched the game via phone yet the issue still persists, there could be a problem with your Epic Games account or your network service.

Kindly try to disable any VPN or proxy servers and use a different network service then launch the game Fortnite to see if it works.

If the issue still persists, I highly recommend you reach out to Epic Games Support for further assistance as they have the tools and resources to properly investigate this case:

When you say it fails to load, can you describe to me what it does when you try to launch the app?

You tried reinstalling the game? You have system update to do?
