What role do 'feedback messages' play in OutSystems mobile applications?

Feedback messages are essential in OutSystems mobile applications as they serve the primary function of communicating status or results to users. These messages help foster a better user experience by providing immediate and clear information about what has happened after a user interacts with the application, such as confirming that a task has been successfully completed, indicating an error, or signaling that an action is in progress. This immediate feedback is crucial for user engagement and satisfaction, as it helps users understand the application's responses to their actions and guides them in navigating through the application.

In contrast, the options related to user authentication, background processes, and data storage do not align with what feedback messages are designed to accomplish. User authentication typically involves security mechanisms to verify the identity of users, background processes refer to tasks that run independently of the main application thread, and data storage management is about handling how data is saved and retrieved. Therefore, these functions are distinct from the purpose of feedback messages, which is solely focused on conveying information to users regarding their interactions with the application.
