Hello,
It seems the “XP reward device” disappeared for creative world or UEFN.
Is this temporary ? Only if not enrolled ? Why ?
Is there somewhere information about that modification ?
I heard about this when UEFN was released, and it has affected my map that I converted from creative to UEFN as well. Strange thing about mine is that I had XP devices in creative that actually carried over to my UEFN map. I could configure them all I wanted and even direct bind them to trackers, but they don’t work in my test-game.
Unfortunately I have no idea when the feature will return. My best guess is that we’ll just have to wait until some future update. After all, UEFN is still in only the very earliest open beta stages.
The device were available last week in UEFN.
But since 24.10 Release Notes the device disappeared… But nothing in the patch note…
So the real question is : How to add XP in our maps now ?
Maybe it is to avoid the real XP mess for all maps from creators 
Seems like they are opting to just doing time based XP for right now. Probably still trying to figure out the best way to allow creators to give out XP with UEFN. https://create.fortnite.com/news/uefn-islands-now-grant-xp?team=personal
