Yes, we’ve done a lot of testing and unfortunately it’s become clear that despite claiming otherwise, most NAS drives don’t implement file system notifications reliably. If you set up a linux machine and a samba share this works, but unfortunately even the major NAS manufacturers we’ve tested (Synology and QNAP) don’t seem to behave the way we’d like.
We’re working on a new strategy for our upcoming 1.2 release that will hopefully resolve this issue completely. I’m not going to say a lot more until we actually see it working, but know that we’re aware of this issue and don’t intend to leave everyone restarting Roon or digging for Force Rescan a lot longer. Appreciate everyone’s patience on this.
