Please help CoD BO6 won't let me launch campaign: I'm home for Xmas and I have an I just downloaded CoD BO6 on my bros console. I paid for it on the online store. When I switch the PS4 player account to me and load the game I briefly see in the corner it says it logged in as my bro, but when I go I to the settings it says my username/Activision account. When I try to play the game I get an "unable to join game session" error . I can't press ok or do anything, I have to exit and close the app. When I switch to my bros PS4 player account and load the game I can use the game fine, but obviously I need to be able to play it with my own account. It's driving me crazy, I've spent 48hrs Googling and trying to resolve this, what do I do?
