Okay, this might be old news to everyone else, but I just figured it out. You know how the first time you log on to fox.com to watch live, it says “you have a 60:00 minute preview pass,” and once that runs out, every time you go on it only has a 5 minute preview pass, which of course wouldn’t allow you to watch the episode.
I realized today that if you clear cookies from fox.com, (on chrome–> settings → privacy and security → cookies and other site data → see all site data and permissions → search fox.com - → trash icon) it will show the 60 minute preview pass again.
Hopefully this will help someone watch live tonight!
(Also, mods, I assume this doesn’t break the piracy rule because it’s watching the episode through fox’s official website, but if it does let me know and i can take this post down).
