I know, I know, silly, but it happened to me so I'm leaving a warning to others: make sure the app you're pushing to is the same app you're checking for changes.

In my case I was pushing to staging and then running a shell on production and not understanding why the static files didn't change.

(It started with a real issue where static files didn't change when I pushed a new version, but it was probably a one-push fluke, and it only kept me going in circles for another hour because I was testing the wrong app.)
