No elevation chart as advertized – Road Trip Planner Viewer Review

I downloaded the app for the elevation feature that is advertised but foe the life of me I can’t figure out how to access it. I wrote to “support “ and all they did was refer me to the online help page which only says that the elevation chart is very handy but don’t show how to access it! So far this app doesn’t appear to be what it claims.
