Hi Nadia,
Thank you for this quick reaction !
I could give you an access to help you check. How can I give it to you in private exchange ?
I told you it was sudden but thinking about it, I believe that I had tested your plugin only when i was adding the featured image in the product page.
I’ve tried few test :
Creating a page without divi builder : ok plugin works
Creating a page with divi builder (and without visual builder) : ok
Creating a page with the front end experience (visual builder) : the category fields are disappeared from the media library.
Hoping that this could help you
I give you back a star for this quick react ??
