Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a system-wide issue. Is this delay consistent across all Android devices and versions?

Why it matters: Helps determine if it's a global Android problem or specific to certain devices/versions. Expected answer: Yes, it's consistent across all devices and versions. Impact on approach: If consistent, we focus on core Android systems; if not, we investigate specific device/version factors.

• Considering recent changes, have there been any major Android OS updates or security patches released in the past month?

Why it matters: Recent updates could introduce bugs affecting notification delivery. Expected answer: A security patch was released two weeks ago. Impact on approach: If yes, we'd prioritize investigating the recent changes and their potential impact on notification systems.

• Thinking about user behavior, are users reporting this issue, or is it based on internal metrics?

Why it matters: Helps understand the visibility and impact of the problem from a user perspective. Expected answer: Both user reports and internal metrics show the delay. Impact on approach: If user-reported, we'd prioritize immediate communication and quick fixes; if only internal, we have more time for thorough investigation.

• Considering system performance, has there been any unusual network activity or server load recently?

Why it matters: Network or server issues could cause notification delays. Expected answer: No significant changes in network or server metrics. Impact on approach: If no changes, we'd focus more on software-related causes rather than infrastructure issues.
