@danny 
my advice is then to put this into https://roonlabs.com/pricing.html since it’s not obvious at all to upcoming/new users. Not to me in fact.
It’s pretty common that if you subscribe to a service it’ll last until the service provider will be gone (no matter what might have ever caused this). Had this way to often in the past.
From your lines I get it’ll end up similar to MusicIP which became reduced in functionality since their servers quit down, but the software on it’S own remained full functional locally with the foreseable limitations.
Think I’ll put the ‘upgrade for a lifetime license’ on my wishlist 4 santa then
(wife being my personal santa, haha)
thanks a lot for getting this explained …
