It sounds like the last time you sync'd the game on Facebook you were at level 305? Or are you on level 404 when you play on Facebook because if you are you can open up the settings page on the Facebook mobile app and go to settings and press on Candy Crush and this sends your progress to your mobile app. Try this out!
