Same issue. Goes through load screen for unlocking Jaden Yuki, then has infinite black screen. Nothing fixes. Even data transfer still puts me at the begining of the load screen and starts the whole process over. I have an unplayable app on my phone now
Hello everyone, I'm not sure if you guys are still having that issue, I encountered it and I had contacted Konami Support via this link: https://www.konami.com/games/inquiry/
Make sure you screenshot your current title screen with your Duelist ID in the top left corner, they may ask you to provide screenshots and to uninstall the game then make a new one with screenshots of both IDs and it work
I transferred my game from an android to an iOS, got the cut scene to work, and transferred back to my android. I highly recommend new players to make a transfer account and code as soon as they start the game
