I'm using composer to include 4 things, meta-box, meta-box-group, mb-settings-page, and meta-box-conditional-logic.
They're all working fine except conditional logic. No errors, I simply don't get the UI in the Builder. Without errors I don't even know where to look.
MB Conditional Logic plugin doesn't have a menu/setting page. Please check if the option "Conditional Logic" is available when you open the Advanced tab of a field setting, screenshot https://imgur.com/UuOmduM
