Compatible With CheckoutWC

I am not seeing what I expect to see when I apply a simple rule of 30% off on all products except for 4 products.

I created Simple Discount – Product Adjustment, Filter >> Products Not In List>>> 4 Products.

Discount >> Percent Discount >> 30

Set the time for it to start (1 hour ago) and ends tomorrow.

1. I expected to see the product page with the discounted price but perhaps this plugin does not do this??

2. I am not even seeing a discount in the cart or checkout page. We are using CheckoutWC instead of the default WooCommerce checkout.
