Modern Warfare PS4 Co-Op Splitscreen?

Greetings, dear ones,

just brought modern warfare and looking forward to the co-op missions by splitscreen with a friend… However, it does not work. Multiplayer goes - but in the main menu under the 3 options "Campaign, Multiplayer, Koop"

I get this message:

"This area does not allow the split screen. Are you sure you want to remove and continue Player2?",

does anyone have a similar problem or can describe me how he has set the settings for the co-op missions so you can play on split-screen synonymous?

Can't play in the split screen
