Thank you for your quick reply!
I appreciate that you offered an explanation and a solution.
However, from my point of view (and I am sure I am not the only one who thinks this way), the situation should be reversed: the developers of the themes and page builders should not modify their work in order to properly function with a certain plugin; instead, this plugin should be modified to work with any WordPress theme, page builder and any other content that is added to a WordPress page or post.
It’s only logical ??
Until then, the Yoast SEO plugin is just somehow useful.
