Gtag not executing conversion events on post purchase page

Hey,

I got the following issue with Gtag for Google Ads tracking on the post purchase page:

According to the documentation, I’ve added a script in settings/checkout/post-purchase page:

XXXXXXX and BLABLABLA have been replaced by real values in the original script


I’ve figured out that the page downloads the Google Ads script but does not fire the conversion event. I have tested the script on the checkout thank you page and it worked. That’s why I am quite sure that the post-purchase page is causing this.

Has anyone encountered this before or has an idea how to solve this?

Many Thanks!
