CartFlows Pro has one solid feature, which is a pre-applied coupon. It gives you the ability to add a coupon when any visitor visits the checkout page. It shows the coupon applied notice as well.

Well, sometimes you want to hide that notice. So, here is a small snippet which will solve your problem. CartFlows has a filter to hide pre-applied coupon notice. Add the below mention filter in your child theme and you are done. Cheers.
