My daughter works in photopass. I asked her your questions and this is her response:
they aren't available for viewing online until they go through our moderation process (people who sit behind computers and edit EVERY SINGLE PHOTO from disney world, disney land and the world of disney in ny). if they're really backed up sometimes it takes a couple of days for the photos to upload. i know that they have been REALLY backed up lately cuz it's getting to be the busy season again. so sometimes they'll have to go through like a couple 100,000 pictures+ a day (each photographer can easily take up to 1000) which really isn't possible....
So be patient. They'll be there.
