I do understand that some plugins may not be compatible with other plugins, and problems do come up from time to time. This is understandable.
What is not acceptable is the lack of refund issued when asked, especially within 24 hours of an original purchase. This shows nothing but greed, and paypal disputes should not be required to resolve problems.
I wish not to bore everyone reading these reviews with technical matters, but temporary admin access was granted, and other plugins you (the developer) advised be removed were removed and the problem still exited.
This plugin was being used on a production website, so we were forced to remove it to restore checkout functionality, and I’m very disappointed you feel this $49 is more important to you than the customers experience.
Again, my recommendation would for users to use the free version, and avoid the paid version unless they are testing on a site that is not live. There are many other plugins that do similar tasks without the yearly fee associated with the plugin.
