Short answer
Adtech consent audit enquiries should identify the website or app, storage and access technologies used, advertising purposes, vendor chain, consent mechanism, withdrawal controls, privacy notices and audit logs. Legal4U cannot decide whether PECR or UK GDPR compliance has been achieved.
