If you are experiencing blank screens or missing tiles in DASH, it is important to check your Internet browser. The first step is to clear your Internet browser cache or history to help troubleshoot an issue. In addition, for the best performance in the system, always verify that you are using the latest Internet browser version available. Oracle supports the latest stable version of the following four browsers: Microsoft Edge, Google Chrome, Mozilla Firefox, and Apple Safari.
Additional information related to Internet browsers, clearing cache, and performance is available in the “Getting Started” category of the DASH Knowledge Base or by visiting Oracle's Browser Document for more information on supported Internet browsers.
