Can’t find this answered previously, apologies if I have missed it.
To make sure I have added all my movies into Collections I can set the display to show All Movies NOT in Collections. Then I can catch any that I have missed. After they are all in Collections I can revert to normal library view.
Now I want to be able to do that for my music library. However, I have not found a way to do this. Library always shows all albums, even the ones already in Collections. I can’t find the setting for All Albums NOT in Collections. It makes the process much harder than for movies.
