Hello @Morgan and welcome to Elfsight Community 
I am deeply sorry for all the frustration caused!
To make it work, you need to add a data-elfsight-app-lazy attribute to the widget installation code. Here’s what the installation code will look like:
<script src="https://apps.elfsight.com/p/platform.js" defer></script>
<div class="elfsight-app-**WIDGET_ID** " data-elfsight-app-lazy></div>
Please replace WIDGET_ID in the code above with the ID of your own widget and install it on your website.
You can find more details in this topic -You now CAN improve your PageSpeed 🚀.
Please check it and let me know if it helped.
Have a great day
