When I focus using unidentified filter I get many albums clearly listed as such. But I also get many without the “unidentified” tag. Thoughts on what I am doing wrong? My thanks.
The “unidentified” info on the album page is simply invisible, although the album actually carries the property (and hence is found by the focus). This is a bug and is fixed in Early Access but not yet in production:
thanks mate - downloaded Early Access. Will see if SongKong can find some data on these “unidentified” Grateful Dead store releases. Cheers.
I want to focus on unidentified albums but don’t see the option in Album Focus (Roon 2.65). There is an option for “identified” but not for “unidentified.” I must be missing something, as Peter_Ryan3 above and others in earlier posts have done it. Please help.
Identified tag. Then click that one, which will invert it to a red 
Identified tag. (You can do this inversion with all Focus tags)
Many thanks. That’s pretty easy, but not intuitive.

I certainly will. Thanks for pointing me to it.
