My drop box does not work instantly with any app. I have to wait for it to "sync". Even tho my taskbar icon shows it updating (pc) the folder contents don't change. Last night I tried something new.
First I had to authorize this app to use drop box. After that I unplugged my iPhone. Next I closed iTunes. Then I plugged my iPhone in which launched iTunes (iTunes option setting) and then went into app and chose the dropbox backup. It only took a moment. Then I synced my iPhone. Another moment later it showed in my folder.
Try that method.
