Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal component. Has this 30% decrease been compared to the same period last year?

Why it matters: Seasonal fluctuations could explain the drop and influence our approach. Expected answer: Yes, it's been compared and is still significant. Impact on approach: If seasonal, we'd focus on year-over-year trends rather than month-over-month.

• Considering the scope, I'm curious about the geographic distribution. Is this decrease uniform across all European markets or concentrated in specific countries?

Why it matters: Localized issues might require targeted solutions. Expected answer: The decrease varies, with some countries more affected than others. Impact on approach: We'd prioritize investigating the most impacted markets first.

• Thinking about user segments, I wonder if this affects all user types equally. Have we seen any differences in registration rates between mobile and desktop users?

Why it matters: Platform-specific issues could be causing the drop. Expected answer: Mobile registrations have decreased more significantly. Impact on approach: We'd focus on mobile-specific factors and user experience.

• Considering recent changes, have there been any significant updates to the registration process or marketing campaigns in the past month?

Why it matters: Recent changes could directly impact new user registrations. Expected answer: A new registration flow was implemented two weeks ago. Impact on approach: We'd closely examine the new flow for potential friction points.
