The green line looks at a cohort of users post-feature change. The blue line targets a cohort of users pre-feature change. It hasn’t been 16 days yet, but the retention chart is populating with data that shouldn’t exist yet. Why?
And how can I make this a cumulative view -- e.g., see retention by day 7, 14, 30 instead of day 0-7, day 7-14, day 14-30?
