Board View GA4 implementation via GTM

Hello, I tried to implement Google Analytics 4 via Google Tag Manager in my app. But it is sends almost 0 hits to GA4.

I’m also using dataLayer to to capture important data about current page.

Any advice, solution or recommend way?

Thank you.

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:


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=""></script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'G-XXXXX', {
    cookie_flags: 'SameSite=None;Secure;Partitioned'

Repace G-XXXXX in both places with your tracking code
