I have the ProClip mount for cable attachment that I got for my iPhone 5 last November. It's been working flawlessly for me since. I got the 5s yesterday, and now the connection keeps cutting in and out. It seems like the cable isn't inserting far enough into the phone, and is causing the connection to be unstable. My 5s charges fine with all the other cables I've tried it with, so I wonder if the 5s is just pickier about how precise the cable fits, or if it's just my phone specifically. It does seem like the cable is recessed maybe half a mm from the top of the holder when it's clicked in place, it's not perfectly flush. Is anyone else having issues with the 5s and their ProClip holder?
