Clarifying Questions (3 minutes)

• Looking at the user base, I'm wondering about the affected demographic. Are we seeing any patterns in terms of user segments experiencing this issue more frequently?

Why it matters: Understanding affected segments could point to device-specific or region-specific problems. Expected answer: The issue is more prevalent among Android users in certain regions. Impact on approach: This would focus our investigation on Android-specific factors and regional content licensing agreements.

• Considering recent changes, have there been any updates to the DRM system or content licensing agreements in the past month?

Why it matters: Recent changes often correlate with new issues. Expected answer: A new DRM system was implemented two weeks ago. Impact on approach: This would shift our focus to the new DRM system and its integration.

• Examining user behavior, has there been any change in the average time between download and playback attempt?

Why it matters: This could indicate whether the issue is related to storage time or immediate playback. Expected answer: No significant change observed in user behavior. Impact on approach: This would suggest the problem is more likely technical rather than user-driven.

• Investigating system performance, have we noticed any changes in server response times or CDN performance recently?
