Thanks for the reply, I actually have a very large library that far exceeds 250,000 tracks. But it doesn’t seem normal to me that an app works according to the number of tracks. Then you could think of a “lite” version of ARC that loads from the main system only objects that can be preselected, for example some playlists (which I consider the most important), a few hundred albums, etc. so that the app works with everything, otherwise the advertising on the Roon site is quite misleading and no maximum number is specified.
