-Yoink!- 343 I just want to play the beta but every time I go to play the playlist button has a red triangle with an exclamation point in it! And I can’t click on it! I’ve tried everything: restarted the beta, reinstalled it, restarted my internet, restarted my Xbox, and signed in and out. Quit making maps and just focus on fixing this problem! How can I give my feedback or my opinion if I CANT PLAY IT!?!? You have no idea the disappointment I’m dealing with, I downloaded it day one and was so excited to play, and now I’m sitting here waiting for you to fix your problems! The beta is basically over and I haven’t played it! And everyone will have played a ton and I won’t have played it at all. Fix this problem and extend the damn beta! All I wanted was to play halo, that’s all I want to do right now, fix this, please.
I am having the EXACT same problem! Am trying to get this crap figured out 
Been sitting here for the last 30 minutes with the same problem. I get a full game, then it kicks me out. Still have not played a game yet
