My Kindle Fire started playing extremely slow. It would crash after about 5 minutes of playing. I lost all of my boosters. I was almost to level 650. I wanted to uninstall and install again to see if that fixed the issue; however, I wanted to sync to Facebook so I wouldn't lose progress. It would not allow me to even connect to Facebook or contact through the app. It got to the point that I couldn't even play at all. I gave up all my levels to uninstall the game and try to start fresh. I deleted the app from the device and the cloud then reinstalled. So not only is it frustrating to start all over again, but it is still moving super slow and crashing in the middle of a game. I don't know what else to do. I am not having trouble with any other app installed on my Kindle.
