I am rtrying to transfer audio book material from my laptop to my Read2Go app, on my iPhone 5S, using the latest build of iTunes. In previous iterations of this software, when my phone was connected to my laptop via USB and iTunes was open, I could easily select my phone, then Apps, then Read2Go and I then had facilities to select a file from my PC to transfer over. With the new iTunes, I cannot find this facility, despite selecting my phone and Apps. Has anyone managed to work out how to do this? I would appreciate any step-by-step instructions. The same scenario would be used, to transfer a document, from a PC to the Pages App on IOS, but again, this does not seem to be straightforward under iTunes 12. Any help is gratefully received.
