Hi, I am trying to join MP and I just can't, it doesn't join and it says unable to join session, for every session I am trying.
What do I do?

Check your NAT type on your wifi and make sure it says open

Had this problem before. Make sure you back your shit up, and delete and re download the game. I know it’s a Major L, but it’s only way I fixed mine. Hope you figure it out
