Hey there, if you are using Android, you should be able to just tap on the installer of the new version and it should instead prompt you to update the game you have installed already. There is no need to uninstall and reinstall the game, in fact doing so will cause your user data (save data, in-game options) to be reset.
If you are on PC platforms, the game is currently not an installable type, so you can simply launch the new executable and enjoy the new update while keeping all of your user data intact.
