• Looking at the timing, I'm thinking there might have been a recent app update. Has there been any significant changes or updates to the app in the past month?

Why it matters: Recent changes could directly impact user behavior. Expected answer: Yes, there was an update two weeks ago. Impact on approach: If confirmed, I'd focus on analyzing pre and post-update metrics.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 4-minute drop consistent across all user segments, or are certain groups more affected?

Why it matters: Helps identify if the issue is universal or specific to certain users. Expected answer: The decrease is more pronounced among newer users. Impact on approach: I'd prioritize investigating onboarding and new user experience.
