No variation swatches in product list – products widget

Hi There!
I’m a new customer, just bought the pro version of the plugin. I was mostly interested in it since unlike other similar plugins, it seems in your demo, that the variations can also be shown in “related products” widget, in products “cards”, under a single-product page-template.
Alas, I am not able to make it work: My single product page is built with Elementor, and it contains a widget called “product related”. It shows related products but under variation products, there’s no variation swatch. I’ve also tried other widgets like simple products list widget, but the result is the same.
I’ve tried to alter the settings of-course and enable the VS under , to no success.
I’d really appreciate your help and support with this.
Thanks,
Chen.
