I agree Roon's support model is not geared towards quick response and it's under-resourced. That may change over time with their acquisition. I've tried to use it multiple times but their support ideas always revolve around stripping down the network and stripping down the library. That's significant work...I can see the logic, but that's not seemed to help anyway.
Plus these problems seem to propagate with new releases...fix a problem once and then a similar one pops a few months later.
I get the sense that, as above, the product is so complex they can't really tell what's going on either.
My OP was more about the locking down of the Roon forum than the product albeit the product drives the comments on the forum. Roon itself is a mixed experience with extreme highs and lows.
