Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be related to the recent software update. Can you confirm when exactly the update was rolled out and if it was a phased rollout or all at once?

Why it matters: This helps pinpoint the exact timeframe and scope of the potential issue. Expected answer: The update was rolled out two weeks ago in phases over 3 days. Impact on approach: A phased rollout might indicate issues with specific user segments or devices.

• I'm curious about the nature of these connectivity issues. Are users reporting specific error messages or just general inability to connect?

Why it matters: This helps identify if it's a specific technical issue or a more general problem. Expected answer: Users are seeing "Unable to connect" errors and app freezes during sync attempts. Impact on approach: Specific error messages could point to particular API or network issues.

• Considering user segments, are these issues more prevalent among certain types of users or devices?

Why it matters: This could indicate compatibility issues with specific hardware or user behaviors. Expected answer: The issues seem more common among Android users and older device models. Impact on approach: This would focus our investigation on Android-specific changes or compatibility issues.

• I'm wondering about any changes in our backend infrastructure coinciding with the update. Were there any significant changes to our servers or APIs around the same time?

Why it matters: Backend changes could be contributing to or causing the connectivity issues. Expected answer: There was a minor API update to improve data sync speed. Impact on approach: This would lead us to investigate potential incompatibilities between the app update and API changes.
