In DASH, you may need to clear your Internet browser cache or history to help troubleshoot an issue since DASH is a browser-based system. This “Clear the Cache in Most Common Web Browsers” Knowledge Base article provides instructions to do this. When troubleshooting a DASH-related issue or error message, following this process is always a recommended first step to try.
Note: When clearing your Internet browser cache or history, it is also important to close out of the Internet browser window(s) fully before re-opening it to try accessing DASH again.
