file-transfer cordova plugin is not working on Android

Description of the problem: Downloading a file in the Ionic 4/Capacitor application with file-transfer cordova plugin is not working on Android. It works fine on iOS but immediately fails with 401 error on Android. I tried to debug it in Android Studio and it looks like this plugin methods are not even hit…

You need both, the <access origin="*" /> and whitelist plugin.

Thanks for looking into it. In res/xml/ there is a config.xml, if you manually add the <access origin="*" /> there, does it work? If so I’ll just add it to the generated config.xml.
