How to Fix the GA4 Rogue Referral Problem in SPA Websites

Summary

The rogue referral issue impacts GA4 in single-page applications. Despite not creating a new session with a change in attribution, GA4 considers new attributions. This issue arises due to GA4's attribution dimensions with user, session, and event scopes. Changes in attribution during a session affect event-scoped dimensions in reports. GA4 uses the last-known attribution from a previous session for the current one, even if it differs from the session-scoped attribution.
