Pixel Helper said the tag fired. Chrome Network never requested facebook.com/tr.
GTM preview said the Meta tag fired. Pixel Helper painted a green PageView. Events Manager is empty, and the ticket says the Facebook pixel is not firing. Those three tools are not looking at the same object. The GTM loader is googletagmanager.com/gtm.js?id=GTM-XXXX . That request proves a container script was fetched. It is not a conversion.

The Meta tag fired but the Pixel Helper showed no evidence of the Facebook pixel firing. The Chrome Network log revealed no request to facebook.com/tr, suggesting the pixel was not firing. The Pixel Helper and Chrome Network tools were providing conflicting information, indicating a discrepancy in the tracking. The GTM loader was fetched from googletagmanager.com/gtm.js?id=GTM-XXXX, confirming the container script was loaded.
The Meta collector URL was www.facebook.com/tr, while Google Analytics 4 used google-analytics.com/g/collect with v=2 and a tid starting with G-. TikTok and Pinterest collection URLs were also provided. The issue could stem from the collector URL being absent, cancelled, blocked, or never queued. To debug, locate the correct collector URL, ensure it is present and not blocked by an extension, and verify the container ID is correct.
If the loader is present but the collector is missing, the tag did not send the pixel. Double-check the collector URL and lint it to identify potential issues.
