The app is necessarily linked to the Amazon App Store app. If you are not logged in there, the app has uninstalled or just no Internet (ie can not log in AppShop) because it is just somewhere in the middle of nowhere or in Bastelkeller can ElectroDroid not use, although there technically would be no reason ( except DRM bulls ***).
