I posted on another post in this forum about not being able to play squads since upgrading to ps4 from ps3. It was deleted, and a post from FlavaSpinkes was there asking about my friend and myself upgrading ghost from ps3 to ps4.
I had major problems with Black Ops 2, when it came out. Now I can't even play against my clan on squads, and my clan leader upraded to ps 4 also! This is the last game I am buying from Activion!
