Players have been experiencing the issues since the release of the game’s last major update on April 28.
“We’ve rolled out a fix to resolve an issue with connections and long wait times while matchmaking in #ModernWarfare and #Warzone lobbies and will continue to monitor,” Activision Support tweeted on Saturday. “Thanks for your patience.”

Update, May 4: Activision said on Monday that it’s “still looking into” connection and matchmaking issues which persisted over the weekend, while a number of Modern Warfare and Warzone players have reported encountering an XP bug which is preventing them from levelling up their Battle Passes.
“The team is aware of the chat issue and working to get it resolved! Please just hang in there for now and stay tuned to future patch notes for updates.”
Details of known issues, patch notes and playlist updates can be found on developer Infinity Ward’s Modern Warfare and Warzone Trello board.
April 28’s 15GB Modern Warfare and Warzone update replaced the battle royale game’s Bounty contracts with a new Most Wanted player contract and added an Armour Satchel allowing players to carry up to eight armour plates instead of five, among other features.
A follow-up patch removed the Most Wanted contracts and reinstated Bounty ones, although it’s unclear if Infinity Ward made the change in response to player complaints or because the feature may have been bugged.
Thirteen Call of Duty Warzone playlists were uncovered via a datamine of the game’s files earlier this week.
They include ‘Classic BR’, which disables features such as Plunder and the Gulag, and ‘BYOL’, which allows players to start the game with their loadout of weapons and equipment.
Infinity Ward studio narrative director Taylor Kurosaki has said Call of Duty Warzone will “connect” the franchise’s various sub-brands such as Modern Warfare and Black Ops in the future.
The studio is currently running a Double XP weekend for Modern Warfare and Warzone, including double XP, double weapon XP, and double Battle Pass tiers.
Activision is also currently looking into an error some Modern Warfare 2 Campaign Remastered players are experiencing on PC.
“We’re actively investigating an issue with MW2 Campaign Remastered where some PC players are receiving an Out of Memory error,” Activision said on Saturday. “Stay tuned for updates.”
The publisher has said MW2 Remastered doesn’t include an online component because it wants to focus on building “one unified online multiplayer playground” with 2019’s Modern Warfare, which already includes several updated versions of Modern Warfare 2 maps. It also plans to add more classic Call of Duty maps in future Modern Warfare updates.
Call of Duty: Mobile Season 6 launched this week. Titled Once Upon a Time in Rust, the western themed season will include two new maps and three fresh modes, plus various events and challenges.
