Hello, I never received a notification of your reply.
I have tried to use the builder in combination with the regulare Metabox plugin. It’s not what I am looking for, I don’t get them to output even when I use the code you’ve provided. I have no use for this plugin and I’m sticking with ACF. If it’s still possible for a refund I would like one. If not, than that’s a bummer. I know I’m late but I tried working with it and I have decided that ACF is much easier for the things that I want to accomplish so I’m sticking with that.
