I figured out what the problem was with MW MP content.I had to recently reinstall a bunch of data packs for Warzone. I uninstalled MW at this point just to save space. I'm half tempted to remove Warzone at this point as I rarely play.
On WZ we can play Alcatraz just fine, but anytime we do Verdansk we have connection issues, get kicked, turns your console off, etc... ridiculous.
