What this tests. The default Google Tag Manager install, which loads the container script straight from googletagmanager.com.
Ad blockers block this setup often because Google's domain is on most common block lists. We load the container GTM-T3X85M in your browser and watch whether the tag-manager script loads and whether the GA4 measurement request reaches Google. Results depend on your specific ad blocker and its rules — other visitors may see different outcomes.
