Critical
Non-compliant tracking after consent was rejected GCM_010

Affected: Exponea

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 does not update in place after the consent choice GCM_008

Affected: lazy_reload

Call gtag('consent', 'update') immediately after the visitor's choice, with the correct values for both accept and reject. Do not rely on a page reload: it creates duplicate pageviews and breaks session attribution.

Warning
Non-compliant tracking before consent GCM_009

Affected: Exponea

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.

Warning
Vendor contacted before consent without identifiers GCM_012

Affected: Google Ads

No identifier was observed, but the visitor's IP address and page context still reached a third party before consent. To be compliant under this check, load the vendor only after consent.
