GA4 Consent Mode V2 May Lead to 90% Daily Data Loss if Not Properly Implemented

Summary

Implementing Consent Mode V2 (CoMo) on low-traffic sites may lead to irreversible data drop, potentially losing up to 90%. CoMo prerequisites include collecting 1,000 events per day with analytics_storage='denied' for 7 days and having 1,000 daily users submitting events with analytics_storage='granted' for 7 of the past 28 days. CoMo isn't a GDPR requirement and may render data insignificant for reports.
