I'am a elementor pro user and a lot of styling is far better organised and integrated in elementor pro than in this theme. There is alway a fight between elementor styling and theme styling with the pro version.
So it's my fault to choose this theme and be not happy with it. Theme developers should sell there addons for sliders and portfolio widgets compatible with elementor pro. That's always the reason why i buy a theme. After buying i mostly return to default elementor and code myself.
