Hi Tony
First, thank you for taking the time to evaluate our plugin and reaching out to us.
When a user clicks an ‘Add to Cart’ button, the Pixel event is sent to Facebook prior to executing the WooCommerce Add To Cart action.
This will also work properly when the ‘Redirect to cart after page successful addition’ is checked.
Please let us know if you have any other questions regarding this product or your specific setup.
Thank you,
Jacob
