When the official sign-in does not work for an account, Jellyscribe signs in through the Letterboxd website instead. Since Letterboxd changed its sign-in page, that fallback has failed every time with "The form on this page had expired", so those accounts could not sync at all. Jellyscribe now handles the new sign-in page, so these accounts sign in, log films and save ratings again. Accounts that use the official sign-in were never affected.
