The script tag is not in the head of the html document when JS aggregation is turned ON. The Iframe with the Google tag is rendered properly, but the enabling tag cannot be soon in source, tag manager fails to discover the tag, Page View events are not triggered.
<script src="https://www.googletagmanager.com/gtm.js?id=GTM-1234565" async=""></script>
The module works great without JS aggregation. Possibly I am not clear on proper configuration, I have tried with and without the file snippet, tweaked the various top-level and container options, to no avail.
I am using the Google Tag Manager preview toolkit, as well as the Google Analytics 4 Real-time preview and debug views in various staging environments and in production.
I am using 7.x-2.1 on Drupal 7.97.

Thank you for any advice.

I have created a quick and dirty module → , with strictly basic functionality, totally inspired by the google_tag module, and it satisfies my rather simple need inside legacy Drupal 7 websites. The biggest difference, regarding my issue in the current ticket being that I generate my snippet files inside a module-sub-directory from a template file: not conventional, but it works with my aggregation and caching scenario.
