ERR_CLEARTEXT_NOT_PERMITTED while opening an external link

Ionic Framework ionic-v3
1

Hi,
I have an Ionic4 app with some banners, when I click on a banner, a site should open in the browser of the mobile.
The URLs are opened with the command:

window.open(bannerUrl);

The problem is that not all the sites have the https version, so on Android 9 when I click the banner I have the error:
net:: ERR_CLEARTEXT_NOT_PERMITTED

I have already done these modifications on the config.xml file:

<widget id="..." version="01.00.48" xmlns="http://www.w3.org/ns/widgets" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:cdv="http://cordova.apache.org/ns/1.0">

..
    <platform name="android">
        <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">
            <application android:usesCleartextTraffic="true" />
        </edit-config>
        <allow-navigation href="*" />
    </platform>

But the problem persists.
How can I open an external Http link on android?

It seams that opening on Android the link in this way:
this.iab.create(banner, '_system');

it works.
However with the previous configuration of the config.xml file.
