There’s intermittent latency with Qobuz on Roon. Here and just here. A banner flashes saying that Qobuz is loading slowly.
Tidal always works fine. Local files fine. Qobuz on Qobuz app fine.
Restarting does help. As does signing in and out. (Haven’t done this scientifically, but it does seem to work.). Also the problem goes away and comes back by itself.
My DNS points to my router. (Upon reading older post, I checked this.)
