How to identify photos not in an album incluing shared albums?
I know how to identify photos that aren't saved in any album - by creating a smart album as explained in this thread - https://discussions.apple.com/thread/7544290
However this doesn't appear to work if the images in question have been placed in a shared album - so is there a way to identify photos not in ANY album?
Thanks to anyone who can shed light on this :)
