Daily Sudoku

Pogo Daily Sudoku is not keeping my progress. Yesterday, I finished all the games for the day (6 puzzles) and when I go back in the today, it told me I had missed a day and wanted me to buy flames to restore my progress. Plus, I had to use a key to unlock yesterday's puzzles which I had already completed. Any help would be greatly appreciated. I was already well past a 300+ daily streak, (I have never missed a day since the game was introduced).
