Invisible Transition in Lock Screen Notification Grouping

The lock screen presents notifications as individual cards arranged in a vertical list. Each card displays content from one alert, stacked sequentially as new ones arrive.

Glances at the lock screen reveal this consistent lineup, with cards accumulating and dismissing as interactions occur, maintaining a steady flow.

The list persists across device uses, showing alerts in their straightforward sequence.

Notifications from the same source now form a single entry with an expansion handle. This consolidated view takes the place of separate cards.

Expanding the entry displays the collection inside, but the lock screen surface shows grouped items instead of the original individual lineup.

The notification display on the lock screen operates as grouped stacks by source, differing from the prior ungrouped list, with the shift unmarked.
