Vast, vast majority of Roon issues are either user or network issues, I've not had single Roon caused issue in a few years of using it, only time I had issues, my network to blame. Roon forums will also prove this out, Roon pretty much as foolproof as it gets.
Sorry but I couldn’t disagree more with this. Roon is great but those who post saying they’ve never had a problem are just lucky. Plenty of power users have had issues too. If it’s a network issue, why does restarting the software resolve it temporarily?
