Y'all, is it time for Lottie in Preview?

I’ve followed Lottie’s instructions for placing an animation on a webpage. I placed their code into a Custom HTML block on an Unbounce page. The animation is not showing in preview.

Anyone else have experience using Lottie on Unbounce? Will the animation only play when the page is published?

Hey, PH_Lovejoy
Please, check the page after publish because sometime it works after published.
If further its not work then you can contact with me via shuvochowdhury8334@gmail.com
