Hello.
We add configurable option to one of our product. We set monthly pricing for product and option (screen1 and screen2) - you can see this on screenshot.
But when we try to change configurable option on the use side - we get zero invoice - screen3 and screen 4.
How can we fix that problem?
In version 3.1 did a lot of changes. And if you checked the script imports and finalized it would be to work with the new version, a lot of people would thank you.
