I deleted my previous 5-star review.  After the latest update, I lost many scanned Beys, had to repurchase in-app items (stadiums), Avatar Track and win/loss record no longer works correctly for all but two Beys.  In short, six months worth of having a GREAT time playing and progressing through the game has been lost.  Patiently waiting for bug fixes, but losing hope that this once-great game will get turned around.
