This post is from the WWDC26 Widgets & Live Activities Q&A.
is there a documented way to schedule when a live activity changes?
I have observed other apps that can update their live activities, (countdown timer that changes at 0:00 to 'Timer Complete')
I've observed apps that can do this without using a server (my device was in airplane mode) and while the app was backgrounded.
but I cant figure out how to do it in my own app
