KLM 1777 registration PH-AXB | Airbus A321neo Plane age: 1 month From Amsterdam to Berlin

It is true that the cabin of this new plane is more spacious than that of the KLM Boeing 737s.

The flight attendant at the front of the plane, after three attempts, failed to make the announcement to inform passengers for the approach to landing.
Why could he not do it without the help of the cabin attendant. I think she knew the reason.
Why? That is the question
