Critical
Non-compliant tracking after consent was rejected GCM_010

Affected: Google Ads

After a rejection the affected vendors must stop setting identifiers and sending measurement, or run only in a verified cookie-less mode.

Warning
Consent Mode default is missing GCM_001

Call gtag('consent', 'default') with denied values before GTM or GA4 loads, so the initial consent state is explicit.

Warning
Consent state was not updated after the banner choice GCM_003

Make both the accept and the reject button update the consent state through the GTM Consent API or gtag('consent', 'update').

Warning
Non-compliant tracking before consent GCM_009

Affected: Google Ads

The affected vendors set an identifier or sent measurement that is not verifiably cookie-less before the visitor chose. Load them only after consent, or configure a documented cookie-less mode that sends no identifiers.
