Add to Cart Shortcode

Dear SoftSprint,

The plugin works fine when I am adding the product from the category listing or the product page, however, I am using an Add to Cart shortcode which is documented here:
https://stackoverflow.com/questions/72446880/add-woocommerce-product-to-cart-by-sku

It is outputting the ‘Add to Cart’ button to the page, as the shortcode is intended to do, but it isn’t adding the redirect to the button. I assumed it would because it is going through the process of Add to Cart but clearly there is something about the ‘hook’ that is different.

Are you able to advise what I would need to do to make this work please?

Thank you.

Rob
