i´m not able to find any solution that solves my Problem.

I use Firebase and Facebook to sign up to my app.

When I first sign up to my app, i get the following screen:

Facebook First Login-Screen

I sign out from Firebase and Facebook using the following Lines of Code:

FirebaseAuth.getInstance().signOut();

LoginManager.getInstance().logOut();

When I´m trying after that to sign in with Facebook again, I get the following Screen:

Facebook Second Login-Screen

I´m only able to continue with the Account I used before.
I want to come back to the first Screen, where I have to enter E-Mail an Password so I could Sign in with another Facebook Account if I want.

On Stackoverflow I found the following promising Code:

FacebookSdk.sdkInitialize(getApplicationContext());

    if (AccessToken.getCurrentAccessToken() != null) {

        new GraphRequest(AccessToken.getCurrentAccessToken(), "/me/permissions/", null, HttpMethod.DELETE, new GraphRequest.Callback() {

            @Override

            public void onCompleted(GraphResponse graphResponse) {

                AccessToken.setCurrentAccessToken(null);

                LoginManager.getInstance().logOut();

            }

        }).executeAsync();

    }

But this solved also not my Problem.

After that I get the following Screen:

Facebook alternate Second Login-Screen

I would by very thankful for any help and sorry for any English mistakes.
