Prime 4 - Mic send to ZoneOut

One wish would be to be able to send the mic to the ZoneOut. This was already possible in an older OS version. Unfortunately not anymore. Please implement this function again

Have you tried to see in the settings? In the new menu there are many options to turn the microphone to various outputs (headphones etc), it seems to me that there is also something for the zone out. If it was there before then it should still be now.
