The album sorting via ROON ARC is not the same as in ROON (Desktop and Remote)
Of course are the “browser sort preferences” the same in.
Since, this is the first version of ARC, there are refinements and additions coming. I have no idea if those include changes to Album Sorts.
If there is a specific album sort you are missing, you could make a Feature Request for it in that secion.
No FR, the problem is that the sorting should be the same (that is, with the same “browser sort preferencer” of course). Data should always be consistent from everywhere.
What about an alphabetical sort or search at the top of the artists
Artists can be sorted by name
