Please fix the freezing!

Adding my frustration to what others have said about this. Game freezes with last two tiles, and only way to get it started again is to close the app and lose my progress. Ive uninstalled and reinstalled twice - no help plus I lost the hundreds of games Ive played. I have been playing this app for a long time, but I am seriously thinking that I need to find another one because of this problem.
