Please check if your Row level Security roles are matching what role your embedded applications has setup. For instance, if you have "User" as your expected role in your report, and your application attempts to apply a nonexistant role of "Account" to the report. You will get an errorf for each visualization saying: "Can't Display the Visual. See Details."
Hope this helps anyone who has this issue.
