Live Activity Not working on Dynamic Island on TestFlight

Is something wrong with testing live activities on Dynamic Island in iOS 17?

It works fine for devices without dynamic island.

It's a timer countdown. Initially, it didn't show up on the iPhone 15 Pro, but after installing and reinstalling the app it showed up. But now, the timer freezes like it was freezing while it was being tested on a simulator.

Is there something extra I should be doing for the Dynamic Island Display?

P/S: The app uses only Live Activities without the widget.

Realized I need to update the LiveActivity with remote push notification, as the app goes into the background
