Notice for the Display Bug of Double Cards
We are sorry to inform you that due to a display bug, you cannot see the duration countdown of your double BP or EXP card in the team-up lobby. But please do not worry, the card that you use is still effective. You can see the doubled EXP or BP reward and the card’s duration when the game is over. The bug will be fixed in later update. Thank you again for your support to Mobile Legends!
