Currently, we have confirmed the following issues.
・In the Deck Organization screen, when you switch the card information by tapping several cards, there are instances wherein the video would not play.
・In the setting screen, when you set the Graphical Setting to "Low" or "Normal", a gap between the video playback timing and the display of the text in the bottom of the video occurs.
It would be much appreciated if you would check the Official Site and the In-game Notice for more details.
Our apologies for the trouble, but thank you very much for understanding.
