Any news when this will be fixed or it's being even worked on?
I was told that when you send a PDF in to convert it always shows up with Filename - Email address but Kindle CS seems to not have a clue on Mobi files being sent in always showed up with the correct metadata information whether you used Calibre or not.
I've never sent in a PDF so I can't confirm if that is true or not. I just use Mobi files and convert my own PDFs myself.
I just realized something else. I am no longer getting the Personal Documents waiting message either.
