This album by John Williams popped up in my NRFY list. Roon states that it was released 29th May 2020. However, the majority of the tracks are marked as unavailable.
Looking at the album in the Qobuz app (where the same tracks are also not available) reveals the reason why: the album is scheduled for release this coming August.
Treat this as feedback that Release dates and Pre-release dates are not the same thing. I don’t know whether this is fixable in Roon, or indeed whether it is worth fixing if this only happens to the occasional album.
