Yes, unfortunately some players are experiencing a bad performance for this game.
In situations like this the best option is share this feedback and report the problem to the developer, in this case Activision

Hopefully they're going to fix a new update improving the performance

Our xbox one is doing it with Modern Warfare. How can this be fixed?

Hi There,

This seems to be a fairly common occurance on Modern Warfare and the only fix that I've found involves doing these steps.

MODERN WARFARE “YOU DO NOT OWN OR ARE MISSING THE MULTI PLAYER DLC PACK” ERROR FIX | XBOX ONE

On Xbox One you’ll need to perform a slightly different process. There’s no option to restore licenses on Microsoft’s platform, which, regrettably, means that you’re less likely to fix the issue without needing to do a full reinstall.

• Select “My games & apps” on the Home screen
• Locate Modern Warfare on the “Games” tab, highlight it and press the Menu (start) button on your controller
• Select “Manage game & add-ons”
• The following items should appear in the “Installed” section:
  • “Call of Duty: Modern Warfare — Multiplayer Pack”
  • “Call of Duty: Modern Warfare — Spec Ops Pack 1″
  • “Call of Duty: Modern Warfare — Campaign Pack 1″
  • “Call of Duty: Modern Warfare — Campaign Pack 2″
• If you’re missing any, manually search the Xbox Store in order to download them
• Should all of the relevant DLC already be present, you’ll need to uninstall all game content and then perform a full reinstallation

Try it out and see if it helps. All credit goes to Game Revolution.

This did not resolve the issue. I still do not have the option to access Modern Warfare. It only shows options to pre-order Modern Warfare 2, Play Warzone, or Purchase Vanguard. If I view it in the store it says I own the game.
