Hi @kairey1964,
Sure, I will be happy to assist you in resolving your issue with the links within the popup.
When I checked your site, I found the popup was working as expected with a delayed update with iframe loading. However, your added iframe was generating too many errors in the console while rendering the page.

I also found that your site has LiteSpeed Cache enabled.

Could you please confirm if you have enabled CSS Minify & CSS Combine? And JS Minify & JS Combine with Load JS Deferred?

You will have to disable all of them and clear your site cache to confirm if this is interrupting the popup iframe.

If the issue persists, you can switch to Divi Areas Pro. It gives you more flexibility in terms of managing the popup and further comes with different layouts, behaviors, triggers, and integrations, including popup scheduling as well as supporting dynamic elements and iframes.
