Rails for Beginners Part 24

A great tutorial. I'm a little stumped and looking for a little guidance. I followed along with the tutorial and added on <%= button_to "Connect Twitter", "/auth/twitter", method: :post, class:"btn btn-primary"%> and I can get connected to Twitter. Right around the 5:00 mark, I see the button is no longer present and you typed in http://localhost:3000/auth/twitter. Was there some logic added to remove said button? Also every time I type in that URL it just takes me to the no routes matched

The button is addressed in part 27, but still have the issue with the http://localhost:3000/auth/twitter no routes matched
