i still able to continue my game progress on Android after I updated the game, you don't need to uninstall the game before installing the new version.
I'm not uninstalling the game, but when I updated it it comes up a new icon on my screen.
The yellow is old game the red is the updated one. And when I go in to the old one it does not include the same as in the updated one. I'm playing to buy the game, but it will suck if I have to start all over again every time I update it.
It's a really good game!
