I moved from Magento to WooCommerce.
In Magento I had instruction video's for a product.
I use Elementor to make the Product single template an made a view embed code for this.
In this view I have a basic iframe with the dynamic id in it
Yes in the product.
And I found out what the problem was, I needed to set the taxonomy and to this Taxonomy is set by the page where this View is inserted
Now it works!
