PX4 not sending Waypoint Mission Reached Command

I am working with the development of automated control station for the drone-based delivery scenario. I am using predefined mission for achieving this.

Till version 1.5.5, PX4 keeps sending the Waypoint Reached mavlink command (specifying the last successful waypoint) at the frequency of about 4 Hz. However, in v1.6.2 and v1.6.3 I receive this message only if the drone lands successfully in landing waypoint. Is it a bug in PX4? Please, let me know if I am missing something. Thanks in advance.

Its supposed to update it on every waypoint reached. You’re saying it doesn’t update on every waypoint?

Yes, it does not update on reaching every waypoint. It updates only on reaching landing waypoint.
