Troubleshooting Lindy Integration in Embed Preview and Deployment

Question - My Lindy works in the test panel, but it doesn’t work in the embed preview, nor does it work on my site’s embed. Is there a final step I need to do to make it fully deployable? The embed code is on my page (although I had to specify the box dimensions as the 100% x 100% didn’t show any of the text) but it never gets past the first question.
