Hi!
I have tried to create a single product Layout. First time the preview switcher loaded the deisired product. However, after the progress of building the post layout was saved, I was unable to load any product into the switcher. Only the Header and the Footer were visible.
Also, I have saved the template with the assignment to the Product post type, but the products are still having the original Woocommerce design. Maybe I am missing something?

Thanks!
