After I import photos from my iPhone to Elements 15 Organizer, it has an option to delete the photos from the phone. It never works. Even though my is still connected, I get a message that says, "Failed to Connect: Device is not connected or is busy." This has gone on through several versions of Photoshop Elements, on several computers, under Windows 7, 8, 8.1 and now 10, and with the iPhone 4s, 5s, 6 and 7 Plus. It has never worked, even once. I have seen a couple of related questions about this in the forums but never an answer. Is this a known bug that Adobe just ignores, is is there something I've been doing wrong for years? I've attached a screenshot of the error message.
