Are returning visits affected by the delete log feature? We are deleting logs older than 3 months, and I’ve noticed that our sites don’t have data for “Returning visits” (Visitors --> Engagement) after 3 months. The FAQ says that the Unique Visitors metric won’t be available if logs are being deleted, but it says nothing about Returning Visits.
Further, even though Returning Visits is missing for > 3 months, Unique Visitors still has data. Can anyone clarify the returning visits metric and why it might be missing in reports > 3months?
