Just a follow up to my own question. I emailed Photopass about a week after our trip since there were no borders available to add on my IOS system. I was also missing a ride photo and uploaded a photo of us taken right before the ride to help them find it. I have gotten absolutely no response in the 3 weeks since I emailed.
I did keep checking the Photopass site and see that borders and stickers are finally available. That includes a 50th anniversary border, and some 50th anniversary stickers.
So best of luck to anyone needing assistance. It's not going well these days.
But if you're looking for borders, you are in luck (if you have an IOS system).
