Hi @jfp,
I appreciate you sharing how your experience in using one license in more than one location has changed since the release of Roon 1.8.
I am sorry Roon 1.8 in your case isn’t what we hoped it would be. We’d love to help, albeit this late. Please, accept my sincere apology for the delay 
I was wondering if you could please share some details about your QNAP setup, using this post as a guide.
This will provide our technicians with the details they need to make relevant suggestions 
Thank you in advance 
P.S. Thank you @Geoff_Coupe for your help in bringing this to our attention
