• Looking at the timing, I'm thinking there might be seasonality at play. Has this 30% decrease been compared to the same quarter last year?

Why it matters: Seasonal trends could explain fluctuations in sign-ups. Expected answer: Yes, it's been compared and the decrease is still significant. Impact on approach: If seasonal, we'd focus on year-over-year comparisons rather than quarter-over-quarter.

Why it matters: Identifying affected segments could point to targeted issues. Expected answer: The decrease is more pronounced in younger users aged 18-25. Impact on approach: We'd investigate factors specifically affecting this demographic.

• Thinking about recent changes, have there been any significant updates to the app or marketing strategies in the past quarter?

Why it matters: Recent changes could directly impact sign-up rates. Expected answer: A new UI was rolled out two months ago. Impact on approach: We'd focus on the impact of the UI change on user experience and onboarding.
