Has anyone else notice that since the newest version of DTTG came pit, iReader won’t let you send marked up PDFs to it? Anyone else experiencing this?
In response to the original question, note that when you tap “open with” for a pdf, the list of apps that comes up is limited (to 9 I think), and sometimes DTTG may fall off the bottom of the list. I had that problem and had to delete a few of the apps capable of opening pdfs to be sure DTTG stayed available.
