• Looking at the timing, I'm thinking this could be related to a recent app update. Has there been any significant change or update to the app in the past 1-2 weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, there was an update. Impact on approach: If yes, we'll focus on changes in that update; if no, we'll look at other factors.

• Considering user segments, I'm curious about the distribution of this decrease. Is the 50% 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 drop is more significant in certain segments. Impact on approach: If segmented, we'll focus on those specific user groups; if uniform, we'll look at broader issues.

• Given the severity of the drop, I'm wondering about any changes in marketing efforts. Have there been any significant changes in marketing campaigns or user acquisition strategies recently?

Why it matters: Marketing changes can directly impact new user signups. Expected answer: No major changes in marketing. Impact on approach: If no changes, we'll focus more on product and technical issues; if changes occurred, we'll investigate their impact.

Why it matters: Technical problems can severely impact user signups. Expected answer: Some increase in reported issues. Impact on approach: If yes, we'll prioritize technical investigations; if no, we'll look more at user experience and product features.
