PSA - you can rewind Peacock during live action. It helps to put the game into your "Favorites" beforehand, because you might accidentally catch the score on your home screen immediately upon opening Peacock. And because there is no "watch from start" button once selecting a game, you have to open it with tv muted, close your eyes, and hit the rewind button.
Caution: While watching on a delay, if you should close the app before you are caught up, the game will revert to live upon re-opening the app.
