No, it was added just before I made my first post in this thread announcing it was now available.
We understand that it can be frustrating that Roon does not reflect new streaming service content immediately, but the rich interlinked Roon experience would not be possible without deep integration of metadata from our providers; and this requires up-front data dumps from them rather than using their APIs. There is a necessary period of time – from receiving the metadata to releasing it – during which a complex metadata build process runs.
We have reduced the lag considerably in the last year or so and continue to work both internally and with our metadata providers to reduce the lag further.
