Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent system update. Has there been any significant changes to the EFT payment system in the last two weeks?

Why it matters: System changes often correlate with performance fluctuations. Expected answer: Yes, there was a minor update to the payment gateway. Impact on approach: If confirmed, we'd focus on technical issues related to the update.

Why it matters: Segmented impact could point to specific user experience issues. Expected answer: The drop seems more pronounced among new users. Impact on approach: We'd investigate onboarding processes and new user journeys.

• Given the metric specifics, I'm curious about the definition of 'success rate'. Has there been any change in how this metric is calculated or measured recently?

Why it matters: Metric definition changes can lead to apparent performance shifts. Expected answer: No changes to the metric definition. Impact on approach: We'd focus on actual performance issues rather than measurement anomalies.

• Thinking about external factors, I'm wondering if there have been any significant changes in the competitive landscape or regulatory environment recently?
