    All the other documents uploaded together with the faulty one, or uploaded before or after, would get displayed just fine. The content providers who upload these have admin right​. We would delete the document and upload it again, but the issue persists - even if we try on different machines. Then, in a few hours or a few days the system would allow us to upload it and display properly - for no apparent reason. This is a serious impediment to our work. Any ideas why it happens and how it could be fixed?
