I just tried to multi-select albums and remove them from my library and it seemed to work okay. If you select a smaller amount is there any change? Is it only happening when you have hundreds?
In Roon we don’t show any albums that don’t have streaming rights in your region (Qobuz might show albums that can’t be streamed with 30s clips available). We also group together different versions of the same album, so it might look like there is less in Roon even though all streamable albums are still available.
Are there any specific examples of an album you can’t find in Roon that is fully streamable in Qobuz?
