Just got randomly disconnected from a BTB match. Restarted the console. Game took FOREVER to sync my profile data. The Spartan Hub didn’t appear on the Main Menu when first starting the game. It also took forever to “Load” the main menu when it says Press Start. All the Arena and Social playlists also hang on Retrieving Data just to load the playlist data, so there’s nothing there. Internet is fine on computer, other consoles in home, etc.
Edit: After about 15 minutes it seems to finally fixed itself. All is well now.
