Step-by-step explanation:
The dashboard components failing to appear can be caused by a variety of issues. These issues might include but are not limited to: incorrect user permissions, errors in the configuration settings, problems with the data source, or compatibility problems with the software version or the browser being used. To troubleshoot, one should verify user permissions, check configuration settings for the dashboard and its components, confirm that the data source is properly connected and providing the correct data, and ensure that no software updates or browser compatibility issues are causing the problem.
