Hello Daryl,
I hope you're well!
Since you have mentioned that GA4 is working fine for tracking "events pages".
I do not use GA in my org account for some reasons. Have you tried checking your GA admin account configuration for "File Downloads" if you're referring to track the "Add to Calendar" that is event calendar file which downloads?
In GA4, this is enabled by default, so you're probably fine, but if you want to verify, log into your GA4 account and check if file download tracking enabled or disabled. It works in external websites with JS and GT manager.
Wondering why it's "zero tracking" as event page tracking works! And I'm all ears for WWW(WhatWentWrong) / any alternative suggestions for tracking event calendar link on the website built via Cvent platform.
