Extension objects do not export properly in Qlik Sense story.
We have created applications with extensions. This is in a server environment running QS 2.2. The application runs fine and even the stories work properly. However, when you try to export a page that has an extension on it the pdf/powerpoint displays, "Invalid visualization. The visualization was not found on the server: ExtName".
I've installed the extensions on the server so I'm not sure what else to try here.
