Thanks, we will look into it

[demchenkoalex]

So the problem was in the url_launcher. See the setup docs for Android, this will help. I have also added

<!-- Provide required visibility configuration for API level 30 and above -->
<queries>
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="https" />
  </intent>
</queries>

to the example and removed throw 'Could not launch $link';
