"Call of Duty: Addressing Progression Issues and Server Problems"

Call of Duty experienced a progression issue that reset player progress for weapons, Ranked Play, and battle passes, prompting the temporary disabling of Ranked Play and Modern Warfare Zombies modes while the bug is under investigation. An update has been deployed to fix the issue and restore player progress, with minor bug fixes still pending. The outage comes after Call of Duty was declared the best-selling game of January 2024, following Microsoft's purchase of Activision and ongoing challenges with adding Call of Duty titles to Xbox Game Pass.
