Unidentified albums search

How can i find all my unidentified albums?
Have tried Focus, but there is no way I can find them by using that.

@Peter_Leinslie Focus on albums, then go to inspector then select identified and toggle it so it goes pink and has a - sign, that will show everything that is not identified.


It will look like this:

Like Russ said, the ‘Identified’ toggle is green and marked with a + sign by default – clicking on it changes it to pink/-.
