There appears to be a bug for people who have over 100 pages of saves. It looks like they've increased the number of saves per page, and in doing so have bugged something in the save system, so you presently can't move beyond page 100. I have several playthroughs spread over hundreds of a pages of saves (I save frequently). This means I can't play this update at all, because before starting the new content, I decided I wanted to replay another scene from an earlier update, and having done so discovered that frustratingly I couldn't get back to where I finished last time. It's possible to go back, but not forward, until you reach Page 100. That's because both of the forward toggles are frozen beyond that point.
