I had my privacy settings set to "Custom" for wall posts, photos, and some other profile elements.
I excluded a list of people from seeing posts I made and posts other people put on my wall.
When I used the "View my profile as," I wouldn't see the excluded elements.
Once the new design launch, I realized that all these settings were lost - I can do "View my profile as" one of the people on my excluded list, and see the stuff I didn't want shown.
