One thing you could try is to keep your Login Page inside of a NavigationPage, and then instead of running PopAsync() within the Login Page after they have logged in successfully, simply replace the MainPage with your old Navigation page:

In your App class:

public NavigationPage AppNavPage = new NavigationPage(new FirstPage());

public App() {
    MainPage = AppNavPage;
}

In your FirstPage:

private async void ShowLoginPage() {
    ToolbarItems.Clear();
    var page = new NavigationPage(new LoginPage());
    await Navigation.PushAsync(page);
}

In Login Page:

private async void OnCreateClicked(object sender, EventArgs e) {
    bool loginInfoIsGood = CheckLoginInfo(); //Check their login info

    if(loginInfoIsGood) {
        Application.Current.MainPage = App.AppNavPage;
    }
}

Otherwise, I have also done a custom renderer for the NavigationRenderer on iOS to insert toolbar items onto the right side of the Navigation Bar and have overridden some Menu related stuff on Android to change the icon text/colors.
