Adobe will officially stop the support of the Flash Player on December 31, 2020. For more information refer to Adobe’s announcement. Browser vendors, like Google and Mozilla , also announced their support of this Flash deprecation effort.
For Strategy users, legacy Flash-based widgets you haven’t had a chance to convert to other Strategy objects, such as DHTML widgets, mobile widgets, or graphs will no longer be rendered properly starting on January 12, 2021. You are strongly advised to uninstall the Flash Player and convert your legacy Flash content to other supported widgets or graphs in documents as early as you can.
After uninstalling your Flash Player to prevent future security risks, please open your documents with the flash icon (as pictured below) in the design mode, and then open the Document Properties editor to change the Run by default as setting from Flash (deprecated) mode to other applicable modes. Deselect Flash (deprecated) in the Run Modes section and select another proper mode for it.
