Defer is messing up Google Tag Manager script

Hello @guyinpv

The reason why you can not find the script in the exclusion list is that the Google tag is added as an inline script. According to the ID of the script, you are using the Google Sitekit plugin. I was able to recreate the issue and reported it to our developers.

In the meantime, you should be able to exclude the script by adding the following filter to the functions.php of the active theme:

add_filter( 'sgo_js_async_exclude', 'js_async_exclude' );
function js_async_exclude( $exclude_list ) {
	$exclude_list[] = 'google_gtagjs';

	return $exclude_list;
}

With this code added to functions.php, you can safely activate the “Defer Render-blocking JavaScript” feature.
