Third-party services like Google Analytics must be blocked in accordance with privacy regulations if a user has not yet given consent. Use your Usercentrics DPS Scanner to find out which third-party technologies you have running and block them until consent is obtained. Additionally, the bookmarklet in the Tealium extension automatically recognizes all tags that have been implemented in Tealium IQ Management.
As a reference, here is the guide for CMP v1 and v2 with instructions for how to block third-party services manually.
For questions about third-party services using Google Tag Manager, please see our documentation for CMP v1 and CMP v2.
