I don't mind going to the app, but I rarely use it unless it's situations like this, usually more trouble than it's worth, worst-case I miss a few minutes of the game. But I guess I'm naive, didn't realize the final 90 seconds of game time of Tenn-VT would extend for 20 minutes.
I've said it before and I'll say it again, this is 2022, there should be a pop up window that appears on your screen, no matter what TV service you have, asking if you want to switch to the new game, or stay with the current game.
