选择帐户后，Ionic 4 Firebase Auth signInWithRedirect（）挂起

Question

我正在尝试使用Firebase的授权登录服务（特别是google）。我在这里使用一个简单的例子：

google() {
    const provider = new auth.GoogleAuthProvider()
    this.afAuth.auth.signInWithRedirect(provider).then(() => {
      this.afAuth.auth.getRedirectResult().then(result => {
        console.log('signed in', result);
      }).catch(error => {
        console.log('signin error', error);
      });
    });
  }

如果我使用ionic serve运行该应用程序并在浏览器中查看该应用程序，则可以正常运行。当我尝试在具有ionic cordova run android -prod -release的设备上运行该应用程序时（或者如果我通过Android商店将其作为Alpha版本发送出去），则会遇到以下问题

当我尝试使用该服务时，我被重定向到能够选择Google帐户的浏览器。我可以选择该帐户，然后将我重定向到一个空白页面，并显示此确认/警告框：

如果我要按“确定”，则会显示另一个警报框：

在此按钮上按OK（确定）后，它进入空白屏幕，浏览器加载栏固定在75％并挂起。看来我无法重定向回自己的应用。

同样，该问题仅在设备上发生。我尝试使用signInWithPopup（针对Google的建议），但我得到的问题基本相同。我可以很好地使用电子邮件/密码组合。

有什么想法吗？下面是我的package.json，如果其中包含任何提示：
