It appears that the new woocommerce update and your theme have <?php do_action( ‘woocommerce_before_add_to_cart_button’ ); ?>
So if any plugins use the same web hook woocommerce_before_add_to_cart_button it will show twice on the product pages.
I’ve removed this from the woocommerce plugin which was solved my issue for the time being.
Would be appreciated if you could let me know what changed since the recent update to cause this so I change in my child theme rather than editing the woocommerce plugin.
Thanks
