Autoplay lifts watch time but hurts a stability guardrail
A video app tests autoplaying the next clip automatically. The primary metric, watch time per session, is up a significant +9%. But two guardrails move the wrong way: the app-crash rate is up a significant +0.3 percentage points (autoplay strains memory on older phones), and the share of users who turn autoplay off is meaningful.
Should the team ship, and how should they weigh the guardrail regressions?
