Yes and no. All of the plugin instructions had been translated, but when I dragged the widget into my sidebar to set it up, the success message, error message, sign up button, etc…were in English. It didn’t matter to me because those are editable (which is a great feature of the plugin, right away, thanks) and I planned to customize them anyway, but if someone wanted the pre-translated versions, I could see how it might cause a problem.
Let me know if that makes sense. Cheers
