Slow support

I contacted Steinberg Support a month ago, on 26th July 2023, but they haven’t got back to me. With that experience in mind I find it pointless to write to them again asking about the slow support service. Perhaps there is a Moderator here that can clarify the situation.

Here is my request:
Changing Pitch using “MIDI Input creates randomly silent notes with “Acoustic Feedback” “On”

Randomly silent notes when using "MIDI Input” to set a pitch of a note in the Cubase MIDI Editor Window with “Acoustic Feedback” “On” - That is, I can hear some of the notes, others are silint, no sound. This seems to be totally random.

This problem is very old - like many years old. It’s still a problem in Cubase 12.0.70 on Mac M1 Ventura.
