Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent SDK update. Has there been any change to the Android SDK in the past month?

Why it matters: Recent changes could directly impact session duration. Expected answer: Yes, there was an update two weeks ago. Impact on approach: If confirmed, we'd focus on the update's changes and potential bugs.

• Considering user segments, I'm curious about the distribution. Is this decline uniform across all Android versions, or is it more pronounced in specific OS versions?

Why it matters: Version-specific issues could indicate compatibility problems. Expected answer: The decline is more significant in Android 11 and above. Impact on approach: We'd prioritize investigating recent Android OS changes and their interaction with our SDK.

• Thinking about user behavior, has there been any change in the types of apps integrating our SDK recently?

Why it matters: Different app categories might use our SDK differently, affecting session duration. Expected answer: No significant changes in app categories. Impact on approach: We'd focus more on SDK performance rather than user behavior shifts.

• Regarding data accuracy, have there been any changes to how we measure or define session duration in the past month?

Why it matters: Metric definition changes could explain the apparent decline. Expected answer: No changes to the metric definition or measurement. Impact on approach: We'd rule out measurement issues and focus on actual performance decline.
