I have the same problem where I start up the APU on the Airbus A320neo V2 and when I try to shut it back down via the master button, it becomes stuck and the APU doesn’t shut down.

The only way to shut it down is by pulling the APU fire button to force it to shut down.
The bug occurs every time I want to shut down the APU.
