HA Product Options Variants

I have used this app for well over 2 years now. Over the last year, I've had more and more issues with this app conflicting with other apps that help me generate extra revenue in the business. Tech support's only suggestion is to "remove the conflicting app" to avoid further conflict because their algorithm only works a certain way. To have to deal with frustrating answers like this, have no resolution, AND lose out on revenue because their app isn't capturing upcharges is just plain simple unacceptable. I will not be recommending this app to anyone.
