Tapping the Save button lets users add the video to a new or existing YouTube playlist.

YouTube is rolling out a new Shorts user interface that replaces the Dislike button with Save. The company is testing the change with a limited group of mobile users before committing to a potential global release. Those impacted by this experiment will no longer find the Dislike button on the player's main view. Instead, they can reveal it by tapping the three-dot menu. Unlike opt-in YouTube Premium experiments, this update has seemingly been applied to random users.
