Marketo categorized the Type of some of our uploaded PDF files as "application/pdf" and some as "application/octet-stream". In a Discussion post today, their PDF file was categorized as "application/download". Then sometimes when you try to replace the original PDF file with an updated PDF file Marketo categorizes the replacement PDF file as a different type and the "Failed replace of file" error dialog is displayed.
What causes Marketo to classify PDF files as different Types?
