We have identified issues with the War of Three Kingdoms which resulted in some players having trouble accessing the game between 5-5:15 pm (UTC+0); The issue has since been resolved and the game is accessible again. As a result, we have temporarily disabled The War of Three Kingdoms global beta.
We are hoping to restart the feature tomorrow with fresh matchmaking. Thank you for your patience and our apologies for any confusion. We hope to see you on the battlefield soon!
