[SOLVED]
@camilo may i ask you which field (“dynamic data tag”) you used within the products element on archive page?
Variation Swatches needs a hook (before or after the “add to cart button”) for the output.
I see you have an “add to cart” button in your shop, but with {woo_add_to_cart} we only get a link, not the button.
Solution:
You can add hooks via shortcode: Showing Attributes on the Archives Page - #6 by luistinygod
