Ok, I see. So on Android, the game now defaults to the apps' internal sandboxed storage for file saves, so game data is no longer visible to outside applications. In order to export the file, you either have to use the cloud sync option, or get the
helios file manager and use the Game Data -> Backup Game File option that is on the main title screen menu.
I know it is more of a pain, but I had to make the change to comply with security requirements on the latest versions of Android.
