Sync and won't connect to multiplayer

Hey
recently bought your game and found really annoying problems with syncing, messages keep appearing saying I cannot find servers and I cannot sync. I’ve tested with other titles and they don’t have a problem. I love halo so much I want to play the multiplayer so badly, please can u help or update the game soon as possible. Me and the others will be very appreciated if u can soon. Thanks Calum

This is happening to my friend right now, did you manage to fix it? what did you do if so?

whats it say when you go to playlists?
