No Content-Security-Policy meta tag found. Please add one when using the cordova-plugin

Hi,

My app runs ok under Ionic serve but I have this error when running on device “No Content-Security-Policy meta tag found. Please add one when using the cordova-plugin”.

After follow the steps at http://www.gajotres.net/whitelist-external-resources-and-api-calls-ionic-framework/ I have no more errors at the console but nothing happens after the “Facebook login” button pressed on the app.

The error is related to the Facebook login steps with Firebase.

Thanks in advance

Now I put “allow-navigation href=”*" " at config.xml.

It seems to process the authentication and then show this message on console : GET https://auth.firebase.com/favicon.ico 404 (Not Found)

Any ideas ?

Thank you
