Whenever new content or updates are available, it is important to allow these packages to download completely before playing the game or accessing the new content. New content includes DLC packs, title updates, console updates, and compatibility packs. Attempting to play the game or access the content prior to completion of the download can cause errors that may require the uninstallation and reinstallation of some or all of the content.
Xbox One Season Pass owners: If you see a price associated with a Map Pack in the in-game store or the Xbox Store, do not attempt to download the DLC. Instead, please contact Activision Support for assistance.
Be sure to also verify that the DLC pack has fully downloaded.
