Yup, this is a bug.
To be clear, the bug happens when you have someone who:
- Appears in your library as a composer
- Has 0 performances in your library (meaning they don’t have any tracks, albums, or appearances in your library)
In this situation, Roon will present this person to you as a Composer, but won’t give you the switch to view them as a Performer. That’s the bug.
Unlike your library, my library has some Solange, so I get the switch (on the right):
We’re aware of this bug, but I don’t have a timeline for a fix at the moment.
For now, the workaround is to add a performance to your library – any performance, whether it’s an album, track, feature, etc – and then you’ll have access to the Performer view.
Thanks for the report @Robert_Murray and sorry for the trouble here.
