I had purchased a theme recently, and the theme operates entirely with Elementor Pro. If you don’t have the Elementor Pro plugin, it doesn’t function. Themes of this kind shouldn’t be advertised as working with both Elementor and Elementor Pro. Just state that it works with Elementor Pro only, so we know exactly what we’re paying for.
Usually, paid versions of plugins like Elementor Pro are necessary for a few settings at most. However, here, everything is dependent on the Pro version.
Additionally, the theme’s detail page should provide a list of plugins to be used with the theme. We shouldn’t be forced to install 50 different plugins just to build a website.
