What this question tests

Technical and analytical troubleshooting: isolating where in a notification pipeline delivery is breaking down.

Confirm the scope: what percentage of notifications are failing, on which platform, and since when.
Segment failures by stage: app server sending, push provider, like FCM or APNs, accepting, and device receiving.
Segment by user attributes, such as OS version, app version, or region, to isolate a common factor.
Check for recent changes, like an app update, permission change, or a third party push service outage.
Prioritize the most likely root cause based on where the failure concentrates and propose a fix or rollback.

Breaks the pipeline into clear stages, send, provider accept, device receive, instead of treating it as one black box.
Segments by app version or OS to catch a scenario like a recent update breaking permissions on one platform.
Proposes a concrete next step, like checking push provider delivery logs, rather than a vague investigate more plan.

Treating notification failure as one undifferentiated problem instead of isolating the pipeline stage.
Ignoring recent app or OS changes that commonly cause sudden delivery drops.
