App : 5/5 - Customer service 1/5. I use this app on my websites. Works fine on the 1st, not on the 2d because it seems it's not compatible with Best Custom Product Options app. When you need to have more than 3 variants, it does not display over 3 variants...

However, in your case, the app you use for custom variants is not compatible with our app, because the app is not creating variants in a standard way.
