As you know this game is free for PS+ users, ok cool, I bought this when it was on sale in Feb with the season pass.

I have the game finished, story line not all challenges.

Here is the issue, people who got it from PS+ can join my game, but I can not join thiers, I have uninstalled, and re-installed, without the DLC made no difference. I have DMZ my PS4.

anyone wanna shed any light on this?
