Just finished killing the general, hades betrayal isn't unlocking, is the game not complete or is it another bug?

Now i'm unable to do anything.

Recently downloaded this game and starting to enjoy it until i got to the second storyline where somehow people that are level 1 got there before me, and the people that don't know what to do really irritate me, all they do is kill and sometimes just disconnect or stay afk, and when i finally get to join a game they just make you watch the cutscene, like please, i just want to play.
