We have confirmed an issue happening to certain Android devices where Puzzle & Dragons would force quit on select Android devices during normal gameplay. We are currently investigating the cause of this issue. We will inform all players about the results of our investigation in the future, so please check back for further information.
Due to this issue the start time for the Trick-or-Tournament Ranking Dungeon will be delayed. Some players may see the Ranking Dungeon appear in-game at the original scheduled time, but please note that you will not be able to enter this dungeon. If the Ranking Dungeon appears for you in-game at the original scheduled time, we politely ask you to return to the title screen before continuing the game. See here for more information on the Ranking Dungeon.
We sincerely apologize for these issues and thank you for your patience at this time.
