Your question is Owning a Mobile Production Incident. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you owned a production issue in a mobile app that affected users. Walk me through how you diagnosed it, coordinated with other teams, communicated updates, and what you changed afterward to prevent it from happening again.
