Hi,
Thanks for getting back to me with more information.
Is there a woocommerce product page list in the xml on the Addon version? Also can I modify xml in the Addon version?
Yes, you can do in Addon version.
Is the Open Graph included in the free or the Addon version?
It includes in free version.
I got some problems with mobile page speed (just for mobile and cdn + cache system active ) Is this plugin with addon able to solve my problem?
Our WP Meta SEO does not include that feature, you can try WP Speed of light for this issue.
Are Rich snippets editable somewhere or available?
You can edit at Content meta or at each posts/pages.
For more information, please take a look at our documentation:
