Apple TV is a communal device, and there are often several different people who have accounts or profiles on one Apple TV. If you support profiles, follow these guidelines to make the transition from one profile to another perceptible and smooth.
Provide a meaningful experience that subtly reinforces the transition to the new profile. When someone switches to their profile, they don't want to wonder if the transition happened. The best way to confirm a transition is to fade out and then fade in your app so that people have visual confirmation of the change.
