I have found that the Sample only works if on the Woocommerce Product Page eg https://flooringwarehouse.uk/product/xxxxxx, if on another page i.e. https://flooringwarehouse.uk/shop-wood/?filter_cat_0=140&filter_cat_3=98 it does not.
How can I make it work when NOT on the https://flooringwarehouse.uk/product/xxxxxx please?
