Modern Warfare Data Packs not in Microsoft store

Go to the store in your game and download the data pack 1 for modern warfare

Did u remove the data packs for modern warfare from the xbox live store?

You can install the required data packs for Modern Warfare without going to the store. Go to My Games and Apps, find Modern warfare, press the Menu
button on your controller, then Manage Game and the data packs should be in the ready to install list

I had to go to the store and download the call of duty modern warfare data pack 1 to fix the issue

Make sure you have all three of the following loaded. If you have the same experience I had you won't see these packs as options in the Microsoft store via your Xbox, and to make matters worse, if you visit the Microsoft Store on your PC and go to the
Modern Warfare page you won't see them there either. These links take you directly to the packs. You remote load them by clicking on a button on the web pages so make sure you are logged into your Microsoft account first.
