I changed alliance 2 days ago surely before the event started but my name and medals don’t appear on the alliance war page.
Rosters lock when wars announced (in team chat). You joined your new team about 40min before the event battle period started, but about 6 hours after the event unlocked in-game (i.e., you could see the new event name and cards) and wars were announced. You’ll be included on your new team for the current war which was announcement about 12hr ago!
In this new event is working fine. Thank u for your answer.
