When the export has completed, the upload will occur in the background through the Upload Manager. The Upload Manager button displays in the main document window and displays progress via its blue progress bar.
When the upload finishes, you can click the arrow icon to open the URL in a browser. Click
Clear to close the Upload Manager and clear out completed uploads from the list. If there are no remaining uploads in progress, the Upload Manager button is hidden until a new upload occurs. (This is similar to how the Safari download manager works.)
