It’s likely that using GA4 via GTM does not set cookies correctly in an iframe.

Have you specified Cookies Having Independent Partitioned State (CHIPS)?

You’ll probably need to set cookie flags as follows:

SameSite=None;Secure;Partitioned

If you can’t do that in GTM, then you’ll have to use the standard GA4 script and the cookie_flags option instead.

Something similar to this:

<!-- Google tag (gtag.js) -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'G-XXXXX', {
    cookie_flags: 'SameSite=None;Secure;Partitioned'
  });
</script>

Repace G-XXXXX in both places with your tracking code

Thank you @dvdsmpsn ! Will test it and get back with results.

Thank you @dvdsmpsn for the suggestion!!

This worked like a charm. Thank you David!
