Will this work with Woocommerce Bookings Extension?

Hi I think this is exactly what I need. I allow clients to book photography sessions online via Woocommerce and Bookings extension. However I’m finding some people will book but fail to complete the check-out processes.

I’m hoping with a custom message for photography products that remind them to complete the check-out process will solve this issue.

However, after installing and creating a message, I’m not seeing any changes. Messages set to display on the cart page, it’s a product message, I have the product specified, all minimums are set to 1, still doesn’t show up.

I have most recent WP and WC and Bookings extension plus woocommerce Add-Ons extension.
