Yeah idk honestly. I was trying to find that myself, it looks like it’s just whatever game you chose first is on the island. I had to stop following one and the other would appear there, no clue.

Go pats/c’s!

Click the game and then the three dots, there’s a selection for live activity

No it’s not working for a lot of people, pretty disappointing. Download sports alerts and they’ve got a live activity. Using it for pats and Celtics games right now and it’s pretty sweet, unfortunate you need a third party app to do an ios16 main feature at the moment
