• Looking at the timing, I'm thinking this could be related to a recent deployment. Have there been any significant changes to our API or integration in the past two weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, we deployed a new version last Tuesday. Impact on approach: If confirmed, we'll focus on changes in that deployment.

• Considering user segments, I'm wondering if this affects all partners equally. Are we seeing this 30% decrease across all integration partners, or is it concentrated with specific ones?

Why it matters: Helps isolate whether the issue is systemic or partner-specific. Expected answer: It's affecting our top 3 partners more severely. Impact on approach: We'll prioritize investigating those specific integrations.
