The shop base page is a ‘Product-archive’. The WP SEO Title and Meta settings for the ‘shop page’ do not function.
However for the solution: Look under the Post Types tab and scrolling to the bottom under “Custom Post Type Archives” is a note “instead of templates these are the actual titles and meta descriptions for these custom post type archive pages“.
There you’ll find ‘Products’ (i.e. the products-archive)and the meta boxes for Title and Description
Thanks for the answer. I’ve been trying to fix this for some while. There’s 2 problems left: the description appears only on the first page of my shop. The title is on all pages but the description for page 2,3,etc is blank.
