Dear Players,
Currently Version 3.0.1 has been released on the App Store and Google Play. Players who have already updated will see that the game is in maintenance, and not be able to play the game. Players who have not done the update will still be able to play the game.
As such, please refrain from updating to Version 3.0.1 in order to play the game.
We are currently investigating this issue and will announce all further information after we find the cause. Thank you for your patience and support, and we are sorry for any inconvenience and confusion caused.
We hope you continue to enjoy playing Dragon Ball Z Dokkan Battle!
