From June 2026, the Google Signals configuration no longer governs the data flow to Google Ads. Real control shifts to Consent Mode via GA4, specifically the ad_storage, ad_user_data and ad_personalization signals.

The Data Protection Authorities do not allow GA to be treated as a "technical cookie" exempt from consent.
Does the CMP actually relay the user's decision to the Consent Mode signals, or is it merely cosmetic?
