after being greeted with an update pop-up, i had to update the game in order to keep playing, and after doing so, i (for some reason) lost all my app data and because i wasn't going to swap phones any time soon i didn't save my progess which led to me losing my duelist account. All my efforts to get my account back led to dead ends. Thanks a lot Konami for saving me from wasting more time on your addictive, full of overpowered decks game
