Izotope Neutron Visual Mixer not working in Bitwig Studio 4

Another issue hard to fix: the Visual Mixer doesn’t see any Relay

I searched on the web and found a few tips, old and useless
I tried all plugin sandboxing and none worked
I’ll issue a ticket with the support

Did you insert a Izotope relay (or neutron 4) on each of your tracks first?
Visual mixer needs that to work.
(I dont use Bitwig…)

I did it in Ableton Live 11 and it worked
while it is just a blank screen in Bitwig

[DELETED] - Sorry this was an older solution. I found it doesn’t apply to yours.
