If it ain't broke don't fix it. – Cool Sudoku, Jigsaw, Killer, Kakuro, Sudoku X Review

Very unhappy with the recent update. Most of my unused practice puzzles are gone, the app crashes when I try to access Killer and Mini practice puzzles, and I can't submit solutions half the time. C'mon, people. Give these updates some trial runs before you put them up. Sad. This used to be my favorite app.
