When I hook up my iphone (6 plus running the newest iOS) via usb, and click the import button in lightroom, the tab for the iphone says "No photos found". And there most certainly are several dozen pictures in the phones camera roll. This used to work perfectly, every time, something's broken recently.
May I know which version of Lightroom are you using?
Can you check if your iPhone is locked ? If it is, the please try unlocking it.
It's 2015.7. And the unlocking it thing seems to be the correct answer - it works! Thanks!
I'm glad it worked out for you. Feel free to post your queries in the future.
