Hello, Yes indeed, for Android, due to some stupid "security reasons", it forces you to uninstall before installing the update.
So to make sure you won't lose your save, enable the cloud save setting (Main menu/Play/Cloud save)
The problem had fix,i need reboot phone about three time,but,why the new update so latency and lagging as before? Is that bug? Im tap start and just stuck on loading,and need a few second for grid map,,uhuk so sadly T^T
