Can't re-login with Facebook

Environment

• Nativescript: 5.0.1
• Nativescript-Vue: 2.0.2
• TNS Core Modules: 5.0.5
• Android Runtime: 4.2.0
• nativescript-plugin-firebase: 7.4.3
• Device: Android Emulator (Nexus 5X API 27)

Describe the bug When I open the app and login with Facebook, it works fine. But if I logout and try to re-login (without closing the app), it doesn’t work. It seems the method firebase.login() never resolves. I don’t get any error messages. I only get it to work again if I close and re-open the app.

To Reproduce

1. Login with firebase.login:

firebase.login({
   type: firebase.LoginType.FACEBOOK,
   facebookOptions: { scope: ['public_profile', 'email'] }
}).then(user => {
})
.catch(error => {
})

1. Logout via firebase.logout()

2. Try to login again like in step (1), without closing the app

Additional context Digging into the firebase.android.js file, I see that when I login for the first time, the method logInWithReadPermissions is called and after some time the callback onSuccess is also called, indicating successful login, as expected. But when I logout and click in login again, it seems that logInWithReadPermissions is called, but I never get a callback.

@hcgustavo Thanks for the details (and others as well, for chiming in). I must admit that code looks a bit suspicious. I’ll take a look!

I have the exact same issue 😦 Waiting for the reply from Eddy.
