After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
This issue occurs when mixing both HTTP and HTTPS contents in a single web application. When the HTTP or HTTPS protocol of the contents added to the application matches the protocol of the application, the contents display correctly. This is a security feature of browsers to prevent pages displaying a mix of HTTP and HTTPS contents.
