I setup on stape GTM Containers with Tagging Server Url third level domain. Then for to anonymize the user before the data reaches Google Analytics and GA4, I set GTM server side with IP anonymize to true and inserting user_agent and ip_overside at null. Previously in GTM web I had entered IP anonymize to true (see the attachment).
It’s correct? I would like to prevent any user data from reaching google analytics. Is it possible to prevent Google Analytics from writing and save in user > explorer the user ID client that analytics assign to each device?
