• Looking at the timing, I'm thinking there might be a recent app update. Has there been any major release or feature change in the last 1-2 months?

Why it matters: Recent changes often correlate with user behavior shifts. Expected answer: Yes, there was an update 6 weeks ago. Impact on approach: If confirmed, we'd focus on changes in that update.

• Considering user segments, I'm curious about the distribution of the drop. Is the 15% decrease uniform across all user groups, or are certain segments more affected?

Why it matters: Helps identify if the issue is universal or specific to certain users. Expected answer: The drop is more pronounced among users aged 45+. Impact on approach: We'd investigate features or changes that might particularly impact older users.

• Given the competitive landscape, I'm wondering about market factors. Have there been any significant changes or promotions from competing banking apps recently?

Why it matters: External factors could be drawing users away. Expected answer: No major competitor changes noted. Impact on approach: We'd focus more on internal factors if external influences are minimal.

• Thinking about system reliability, I'm concerned about potential technical issues. Have there been any reported increases in app crashes, login failures, or slow performance in the past month?
