After reading this posts I tried this for you. I annotated 1 page and did send it by e-mail. Worked perfectly

Mind you: you have to give it a (new) name. The name of the original pdf is showed, but grayed. Maybe that's why you saw it as a noname.
It took a bit of time for 1 page. If you choose to send 'all', maybe the file became too big?
Hope this helps you.
