I can’t refresh dynamic Island frequently on ios 18, it's worked on ios 17
You shouldn't refresh your dynamic island content so often. It is not designed to be updated so often (battery and performance reasons). If you are using a timer, a formatted countdown is a better option. The system will almost certainly throttle and eventually disregard requests passed that often from your live activity process. We don't publish explicit budgets but around 15 seconds per refresh is much more reasonable.
my app refreshes the Dynamic Island every 0.25 seconds on iOS 17, but it doesn't work on iOS 18.
