• Looking at the timing, I'm thinking this might be related to the app update. Can you confirm when exactly the update was released and if the decrease in session duration started immediately after?

Why it matters: This helps establish a clear timeline and potential causation. Expected answer: The update was released on [specific date] and the decrease was noticed within a week. Impact on approach: If aligned, we focus on update-related issues; if not, we broaden our investigation.

• I'm curious about the nature of the update. Were there any significant changes to the user interface or flow of the health assessment?

Why it matters: UI/UX changes could directly impact user behavior and session duration. Expected answer: Yes, we streamlined the assessment process to make it more user-friendly. Impact on approach: If yes, we'll focus on UX design and user journey; if no, we'll look at backend or content-related issues.

• Considering user segments, has this decrease been consistent across all user groups or are there specific demographics more affected?

Why it matters: Helps identify if the issue is universal or specific to certain user types. Expected answer: The decrease is more pronounced among older users. Impact on approach: If segmented, we'll tailor solutions to specific user groups; if universal, we'll look at broader systemic issues.
