Here’s a quick tip in response to a query in Twitter by Riccardo Mares. By making a small change to the Google Tag Manager container snippet, you can have the <script> element generated by the snippet notify the page as soon as the Google Tag Manager library has downloaded.
Hi @SimoAhava is possible in javascript (from the page) to check (or hook) when GTM has been loaded? Thanks.
