Build trust by accurately representing the urgency of each notification. People have several ways to adjust how they receive notifications from your app — including turning off all notifications — so it’s essential to be as realistic as possible when assigning an interruption level. You don’t want people to feel that a notification uses a high level of urgency to interrupt them with low-priority information.

Use the Time Sensitive interruption level only for notifications that are relevant in the moment. To help people understand the benefits of letting Time Sensitive notifications break through a Focus or scheduled delivery, make sure the notification is about an event that’s happening now or will happen within an hour. The first time a Time Sensitive notification arrives from your app, the system describes how such a notification works and gives people a way to turn it off if they don’t agree that the information requires their immediate attention. Going forward, the system periodically gives people additional opportunities to evaluate how your Time Sensitive notification is working for them. For developer guidance, see UNNotificationInterruptionLevel.

Never use the Time Sensitive interruption level to send a marketing notification. People may have agreed to receive marketing notifications from your app, but such a notification should never break through a Focus or scheduled delivery setting.
