I’ve copied the template files from WooCommerce into the Sage directory under woocommerce/templates and added the WooCommerce theme support snippet to setup.php, but none of my changes to archive-product.php and single-product.php are showing up. I’ve read all of the threads on here that were relevant, but none of the suggestions worked. What am I missing here?
Place your overrides in woocommerce/ and NOT woocommerce/templates/.
