What caused the sudden 30% decrease in user engagement with MoEngage's in-app messaging feature across iOS apps last week?

Introduction

The sudden 30% decrease in user engagement with MoEngage's in-app messaging feature across iOS apps last week is a critical issue that demands immediate attention. To address this problem, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term fixes and long-term implications.

My analysis will follow a structured framework, beginning with clarifying questions to gather essential context. I'll then rule out basic external factors before diving deep into product understanding, metric breakdown, and data-driven hypothesis formation. This will lead to a thorough root cause analysis, validation steps, and a comprehensive resolution plan.

Clarifying Questions (3 minutes)

• Looking at the specificity of the decrease, I'm thinking there might be a recent change. Has there been any update to the iOS app or the in-app messaging feature in the past two weeks?

Why it matters: Recent changes often correlate with sudden metric shifts. Expected answer: Yes, there was an update. Impact on approach: If yes, I'd focus on change-related hypotheses; if no, I'd explore broader issues.

• Considering the iOS-specific nature, I'm wondering about platform differences. Is this decrease observed on Android apps as well, or is it isolated to iOS?

Why it matters: Platform-specific issues require different approaches than universal problems. Expected answer: iOS-specific issue. Impact on approach: If iOS-only, I'd investigate iOS-specific factors; if universal, I'd look at cross-platform elements.

• Given the magnitude of the decrease, I'm curious about user segments. Are all user segments equally affected, or is the impact more pronounced in specific groups?

Why it matters: Segmented impact could point to specific user experience issues. Expected answer: Varied impact across segments. Impact on approach: If segmented, I'd focus on affected groups; if uniform, I'd look at system-wide factors.

• Considering potential data anomalies, I'm thinking about measurement consistency. Has there been any change in how user engagement is measured or in the analytics system itself?

Why it matters: Measurement changes can create false alarms. Expected answer: No changes in measurement. Impact on approach: If changed, I'd scrutinize the measurement system; if not, I'd focus on actual engagement factors.
