Problems with IONIC 2 in various aspects

The big question is: What happened to IONIC after the updates.

A few months ago I started a project with IONIC 2 for a client. Due to some of my mishaps and the client's part too, the project made a stop. However, we are now back to active and I come across several commands that no longer work. For more than 3 days I'm having problems with settings and only now I can run the app on my smartphone with errors.

Well, I'm not here to cry kk so there goes my doubts:

First problem BrowserTab , Ionic's native plugin, no longer works. Once I've run the code successfully before, I just downloaded it from the repository and ran it back on my smartphone, but it results in nothing. It just stopped working. I tried to debug with the command cordova run android --livereload --device , but the terminal closes whenever the app opens on my cell phone (second problem) , being impossible to get any error messages to be able to identify the cause. Here is the code that does not work anymore.

  constructor(public navCtrl: NavController, 
public navParams: NavParams,
private browserTab: BrowserTab) {}

openPage(option) {
switch (option) {
  case 0:
      this.browserTab.openUrl("https://pag.ae/bkjsxHd");
    break;

  case 1:
      this.browserTab.openUrl("https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=8RV2DK95S29LJ");
    break;

  default:
    break;
}

}

I've already done install , I've already installed the plugin browser plugin following the following link Documentation for the browserTab . I run LiveReload according to the here documentation that is not live anything at all.

Anyway, I'm lost. I've done a lot of research and no results. More than 3 unproductive days without knowing what else to do.

Well, below also my dependencies for analysis:

Well, thank you in advance for any help. Because working with IONIC now following the documentation itself is not producing success. I'm waiting ...
