My thinking is that if workaround like changing the path (see: PMS on qnap loses library path after playing one or two source files) or manually forcing a re-index of the DB or in my case “waiting a few days” is what it takes, then by-golly (would never say that IRL), that’s what it takes.
But… but it didn’t used to be so. And it doesn’t need to be so either. Reading thru the forums, this does not appear to be isolated with just QNAP either.
