Having an inordinately large library and multiple endpoints doesn’t mean you’re automatically diving in beneath the surface of Roon’s capabilities, nor does following the breadcrumbs of similar artists, collaborations etc (and that aspect of Roon is great).
And yet, despite things being perfect for you, here’s a chap also running Roon on Windows having endless, persistent issues. I think it’s reasonable to assume he’s not having a great time using Roon:
Nothing has changed here. For many criticising Roon (constructive or otherwise) and asking them to lift their game to address bugs and shortcomings is a cardinal sin met by a barrage of posts implying that the complainant is negative or hallucinatiing or that their network is to blame (which in some instances is correct, but in many instances it has absolutely nothing to do with the problem).
Roon is a business. Your subscription is a business transaction. Things should work as intended and bugs should be fixed. Rather than move things in that direction this community puts the product and its creators on a pedestal and fights to keep them there. The only purpose that serves is to hamper progress which will in the longer term cause customers to churn in favour of other solutions.
