Hello, I am trying to add attachments to a feature service that I have hosted in my ArcGIS Online for Organizations account. I go to the feature that I want to add an attachment to and when I go ahead and choose which file I want and click open, it returns an error message stating "Failed to add attachment". It is only on ArcGIS Explorer online that I get this issue. I can go to the ArcGIS.com Map Viewer and can add an attachment just fine or through a Web application but I cannot with Explorer online. Any suggestions?
