One interesting twist in all this is that crossplay is apparently working to some extent, even though it's not supposed to go live until later this year.

Bungie hasn't elaborated on what exactly the issue is here or when we might expect the game to return, but we'll keep an eye on things and update when it's time to get back into action.
