I've installed gravity forms developer edition and your plugin, added the API key and sub domain for my client's Infusionsoft install. Your plugin reports that my settings work.
However, when I attempt to add a form after clicking on the 'Let's go add one' link the dropdown field called SELECT THE FORM TO TAP INTO does not contain any forms at all.
Is this plugin only compatible with new forms (vs. legacy forms)? All my current forms are legacy forms I believe.
