Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent update. Has there been any significant app update or server-side change in the last 48-72 hours?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, there was an update. Impact on approach: If yes, we'd focus on change-related hypotheses; if no, we'd look at external factors or gradual issues that reached a tipping point.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 30% drop uniform across all user segments, or is it more pronounced in specific groups?

Why it matters: Helps identify if the issue is global or segment-specific. Expected answer: The decrease is more significant in high-value players. Impact on approach: If segment-specific, we'd focus on that group's unique characteristics or recent changes affecting them.

• Given the nature of in-app purchases, I'm wondering about the game's economy. Have there been any recent changes to the in-game economy, such as special offers or events ending?

Why it matters: In-game economy directly impacts purchase behavior. Expected answer: A popular limited-time offer just ended. Impact on approach: If yes, we'd investigate the offer's impact and transition; if no, we'd look at other motivational factors.

• Thinking about technical issues, I'm concerned about potential payment processing problems. Have there been any reported issues with payment gateways or transaction completions?

Why it matters: Technical issues can directly impact purchase completion rates. Expected answer: No significant payment issues reported. Impact on approach: If yes, we'd prioritize technical fixes; if no, we'd focus more on user behavior and motivation.
