In the next section, there are two options: Created on Lock Screen and Viewed in Notes App.
If you choose resume, you’ll see a number of new options. In the first section, you can choose between creating a new note or resuming the last note. To get started, go to Settings → Notes, then scroll down and tap the Access Notes from Lock Screen option. In iOS 11, you can customize how the Notes app works when it’s triggered from Control Center (from Settings → Control Center).
