Xamarin.Auth Google Presenter not closing

IU am using Xamarin.Auth in a Xamarin.Forms app. Everything works perfectly except that the presenter does not close. It simply moves to the background.

I have a LoginVIewModel (MVVM) in my shared project whcih creates the OAuth2Authenticator and the Intercept Activity in the Android app.

In my In GoogleAuthInterceptor Activity in the create I have

protected override void OnCreate(Bundle savedInstanceState)

        // Convert Android.Net.Url to Uri
        var uri = new Uri(Intent.Data.ToString());

        // Send the URI to the Authenticator for continuation


I show the presenter as follows:

var loginUI = App.OAuth2Authenticator.GetUI(Forms.Context);

I have also tried using:

var oAuthLoginPresenter = new Xamarin.Auth.Presenters.OAuthLoginPresenter();

The presenter shows fine using wither way, user approves and I am redirected back to my App and the completed event on the OAuth2Authenticator is called where I can use the account to get the user information as required

private async void OAuth2Authenticator_Completed(object sender, AuthenticatorCompletedEventArgs e)

            // dismiss presenter???

                App.Account = e.Account;

                var oAuthUser = await GetUserDetails();     

                // Add account to store
                AccountStore.Create().Save(App.Account, App.APP_NAME_KEY);

                // Set the App User for this session
                App.User = oAuthUser ;

        catch(Exception ex)

At this stage if I click the application button on my phone I have see the presenter is still in the background. How can I shut it down in the view model once the completed is called or is there some other way I should be doing it?

    I have managed t suppress the CustomTabsConfiguration message by setting the closing message to null; CustomTabsConfiguration.CustomTabsClosingMessage = null; But this does not solve the presenter issue.

    More on this: I can now confirm this works as expected as long as Google Chrome is the default browser on the phone. If I use the native Samsung browser on my Galaxy S8+ then the browser remains open in the background.

    For me Samsung browser is not getting closed for chrome it is working fine. If you find any workaround for that please let me know,
