I think we are having the same issue on our site, https://jamiethetutor.com/contact-us/
We are using Google Site Kit to add our GA tracking on the site. When I check the page source I see the following GA code:
<script type='text/javascript' src='https://www.googletagmanager.com/gtag/js?id=UA-57762112-1' async></script>
<script type='text/javascript'>
window.dataLayer = window.dataLayer || [];function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'UA-57762112-1', {"anonymize_ip":true} );
</script>
I also see another instance of the tagmanager being called:
<link rel='dns-prefetch' href='//www.googletagmanager.com' />
but I don’t think that is causing a problem.
I verified that the Tracking ID is correct.
Do you have any suggestions?
