There was an update coming to Realist in March 2020. CoreLogic built the site from the ground up. Flash will no longer be needed to run Realist. If you enter Realist on a computer, the site will fill the screen appropriately whereas if you need to use it on your phone the site will scale to that screen.
Below are CoreLogic's training videos on the new Realist:
