What critical step did SrA Smith miss after adding comments for the member in LeaveWeb?

The critical step that SrA Smith missed was not clicking the save button. In many applications, including LeaveWeb, it is crucial to ensure that any changes made, such as adding comments, are saved properly. If a user neglects to click the save button after inputting information, all modifications—including comments—will not be stored, leading to a loss of the data entered. This oversight can cause confusion or misinformation regarding the member's leave request and may lead to unnecessary follow-ups or delays. The other options suggest actions that, while they may be relevant in different contexts, do not directly address the essential requirement of ensuring that changes are saved within the system.
