I just upgraded to version 65 and found that Voiceover no longer reads page titles, addresses or previews anymore. Touching the entry in the news feed announces the poster's name (Rolling Stone, or NPR, for example) and any text in the post itself, but nothing at all about the link. I thought maybe double tapping to open the post would help, but even when in the screen with the post, page info is not spoken. This is a major accessibility problem and needs to be reported asap. I urge anyone else experiencing this problem to visit the Facebook Accessibility page, hit the Contact button and fill out the feedback form.
Unfortunately, it seems Facebook is actually getting less and less accessible despite having a blind employee as a lead engineer in their accessibility department
