Dont know if posted sorry if it was.
I can not down load the files from my xbox when on halo 4.It will pop up a message saying halo file is down.Waypoint on xbox and the comp on waypoint lets me down load it from there.Is 343 moveing it from halo 4 to waypoint?
They aren’t ‘moving’ the file sharing from Halo 4 to Halo Waypoint, under normal circumstances they should be coinciding.
Try restarting your router & Xbox and see if you can use file sharing in-game.
