android Tab fragment. Map not showing

Question

All my tabs work properly and looks like the map is trying to work (I see the Google logo in the bottom left, but map is not rendering.

Here are my Fragment activity:

public class BarberMapActivity extends Fragment implements 
OnMapReadyCallback{

    private GoogleMap mMap;

    public static BarberMapActivity newInstance() {
        BarberMapActivity fragment = new BarberMapActivity();
        return fragment;
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.barber_map_tab, null, false);
        SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

        return view;
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(34.0052982, -83.9888499);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
 }

Here is my map layout:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:id="@+id/map"
tools:context=".shopResult.tabs.BarberMapActivity"
android:name="com.google.android.gms.maps.SupportMapFragment" />
