Hello @Ariel_Levin. On your first point, the metadata streams that are sent only incorporate artist and song. If Roon can match this with an album track it knows then it will show this in the now playing screen. Further artist and song details can then be found via the usual Roon methods.
On your second, the way that skip works is the endpoint downloads a chunk of audio comprising 3 or 4 songs so that it can skip through it. At present Roon takes a single continuous stream (tracking in RP parlance) and plays that.
A more complete integration would entail a Radio Paradise specific plugin. There is a long thread here about this; please consider adding your voice to it.
