I use Roon with tidal and qobuz, never any issues. Make sure you have latest updates with each. You can also save playlists and favorites, import and export them from various applications with Soundiiz. This is what I use to transfer playlists from Tidal to Qobuz.
Roon/Qobuz lost 7000 files
I have an Innuous Zenith 3 using Roon/Qobuz/Tidal (haven’t upgraded yet to the new Innuous os). A couple of days ago, the number of saved albums on Roon suddenly dropped from 13000+ to 6000+. As far as I can tell the missing albums are from Qobuz. It took me hours and hours to find and save all these albums. I backed up my Zenith on an external hard drive but Roon isn’t backed up because it doesn’t recognize my external hard drive—only recognizes Dropbox which I haven’t used because it’s expensive to subscribe. I’ve contacted Roon and Qobuz but so far they haven’t offered a solution. I’ve read on various message boards that others have experienced the same problem. If anyone has any advice, I’d greatly appreciate it.
