iOS 16.2 breaks ProgressView(timerInterval:countsDown:) on Dynamic Island or on Always-On Lock Screen

I used ProgressView to display a countdown progress bar in a Live Activity. However, I found that since iOS 16.2, ProgressView(timerInterval:countsDown:) does not update properly in the following situations.

  1. on Dynamic Island (either Expanded or CompactLeading/Trailing)
  2. on the Locked Screen, after the display is turned off (isLuminanceReduced == true)

In these situations, the ProgressView for the countdown is always displayed at 100% and does not automatically update with the time. The problem only occurs in iOS 16.2. And it's confusing for users. Will it be fixed please?

Noticed the same thing, but I thought it might be a "feature" rather than a bug.
