On the Official FAQ Page I can't get any of the book listings to "open up" so I can read the errata.
I noticed this last night on my old iPad mini, but figured it was likely a compatibility problem because it is running a very old iOS and using an old version of Safari. But just now I used my iPhone running iOS 18.5 and I've encountered the same problem.
So I think something is wrong with the page itself.

Edit: I just noticed that the "opening" mechanism is working just fine for both devices on the PFS FAQ Page so the problem doesn't seem to be on my end.

Edit: And while I was adding that last part the problem seems to have been fixed. Thank you!
