Question about Channel Overview in mix console


Can anyone explain the logic behind using the Channel Overview to select viewing areas of the mix console? For me, sometimes it works, sometimes it doesn’t… I thought maybe it was related to what tracks are visible at the time or folders being collapsed or not, but its functionality is appearing random. Sometimes I click on an area and it simply zips to the first channel. Or sometimes it does nothing at all… Is it buggy or am I just not doing it correctly? I have many VST Inst outputs setup that are being fed by many MIDI tracks… and it seemed this would be a really useful way to jump to the part of the console where the output is active based on the visual feedback but it is not proving reliable. Thanks!
