Call to CompassService causing black screen on iOS - gluon

Question

The following call to compassservice is causing black screen (with charge icon visible) on iOS. It might have something to do with recent iOS 12 update?
Services.get(CompassService.class).ifPresent(consumer -> {
});
Adding the call in
public BasicView() {
Label label = new Label("Hello JavaFX World!");
Button button = new Button("Change the World!");
button.setGraphic(new Icon(MaterialDesignIcon.LANGUAGE));
button.setOnAction(e -> label.setText("Hello JavaFX Universe!"));
VBox controls = new VBox(15.0, label, button);
controls.setAlignment(Pos.CENTER);
setCenter(controls);
Services.get(CompassService.class).ifPresent(consumer -> {
});
}
also produces the issue in a newly created project.
I still get the black screen with battery level visible when using 1.3.15 of the plugin and the following console output:
