In my case the thumbnail portrait displayed on ancestry, not the generic placeholder. Nothing displayed in the person's media gallery. When I clicked on it I couldn't get the full size image, and no image with the right name appeared in the tree's media gallery.
How did you recover from your "process error"? On one occasion it "cleared" itself after a full shutdown and attempt at sync-ing. In 2 other cases it wouldn't go away even after after repeated reboots and manual attempts at re-syncing over several days.
