I'm successfully using UIDocumentPicker and can download and open a file in iOS.
However, If I upload a changed file to the web (via pc) and then download it again into iOS it still finds the old version. It does this for about an hour, then if I'm luck it finds the new one. Another PC with the same dropbox account syncs the file almost immediately.
Is there some sort of cache that I need to disable when using UIDocumentPicker or something else that might cause this?
