I'm not sure what the issue is... I have been very good about only buying MFI cables over the past few years, but now when I'm plugging in my 6S Plus, the same places that I charged my 6 (non plus) are working, but I'm getting the "This cable or accessory is not certified and may not work reliably with this phone" message. I guess my questions are... 1) Is this happening to others? 2) If not, have I just bought cables that were marketed incorrectly? The cables are still functioning, but the error message isn't one that I like to see!
