sort order in iCloud shared photo stream
I have an album of photos in iPhoto v9.5.1 which I want to share using the iCloud shared photo stream. I've carefully sorted the photos in the album. But when I create and send the invite for the shared photo stream, it automatically re-orders the photos by date and greys out in the menu all other sorting orders. In other words it entirely ignores the work I put into creating the sort order.
Is there a fix?
