Selfie Stick not working on iPhone 6S/6S Plus
Asking this for my mother who just upgraded from 5S to the 6S. She has a selfie stick and it works fine on the 5S and my sister's iPhone 6, but will not work on her new 6S. When you plug into 3.5 headphone jack and push button, it won't take pictures. I then tested with the 6S Plus I have, same thing, nothing.
Is there a feature somewhere in iOS 9 maybe or the 6S model (or PLUS) that needs to be turned on for the camera to work with this to use the button to take a picture? I can't find an answer anywhere so I thought I would try a post here. Thanks!
