Can't see shared photo streams in Aperture
I have created a number of photo streams and shared them with my wife.
My wife has accepted the streams and can see them on her iPhone.
She uses Aperture on the Mac but cannot see the streams there.
She has the three checkboxes on the photo streams tab checked, and her own photo stream is visible.
Under the web section in the Aperture library browser, photo stream doesn't appear - her Facebook entry shows up, but not photo stream.
Photo stream shows in the recent section of the library browser, but that is just the photos in my wife's own photo stream, you don't see the individual streams that I can see under photo stream under web in my Aperture view.
My wife has photo stream checked in settings -> iCloud on her Mac.
Any suggestions?
iMac, OS X Mountain Lion, Aperture 3.4.5
