Ionic Native, InAppBrowser always opens system browser

Hi guys,

created simple blank project
added the platforms android and ios
added InAppBrowser using ionic cli:

ionic plugin add cordova-plugin-inappbrowser

i try this code but it always opens me the system browser instaed of the in app browser

let options = 'location=yes,toolbar=yes,hidden=no';
let browser = new InAppBrowser(this.url, '_blank', this.options);
browser.show();

here is my info:

ordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.4
Ionic CLI Version: 2.1.18

Ionic App Scripts Version: 0.0.47
ios-deploy version: Not installed
ios-sim version: Not installed

Update:

after some struggle i decided to build the app using the ionic cli and it works perfectly
before that i was using cloud service which seems to have some problems with this plugin on android,
not sure if IOS too

i also succesed to run this app in the ionic view but only if created the InAppBrowser object in the constructor
but i got an exception when i closed the InAppBrowser view.

if someone could tag the developers to let them know
