Hey @Semaxx@Gabriel@Patatorz – as a general rule, Windows picks up changes more reliably than Linux or Mac, but all of this really comes down to the NAS consistently reporting changes back to the machine running the Core. For the most part, we’ve found that most NAS drives do not do this reliably, particularly when the changes don’t involve creating or modifying folders.
We’ve recently added the option to customize how often Roon manually rescans your NAS for changes, which is a workaround, of course.
While this is really a limitation of the platforms involved, we do have some more long term ideas about how we can make this more consistent, but I don’t have any timeframe to offer here, for now.
