The game is amazing and I have had it for awhile now and had no problems. As of today I cant switch screens or it says I have lost all of my progress. I cant do the daily challenge at different citys and I cant do the food truck competition. I have uninstalled and reinstalled the app and it did not fix the issue. I am not quite sure what is going on with it but if it continues I will delete the game, which I do not want to do because I enjoy playing it.
