I’m so glad you have it working now. 👍 embedding is a bit tricky because it’s not quite the same for each setup. Thank you for sharing your experience, I learned from this. Also, @simon is amazing and one of the nicest, smartest and most helpful people I have had the pleasure of knowing. And he also happens to be pretty good with Discourse. 🙂
