Why is the gold on my lightning cable turning black?
I Was bought an iPad Air 2 and a 2 metre lightning cable for Christmas 2016 and the gold little bits on my lightning cable having started turning black and no longer charging my iPhone 6 or my iPad. What is causing this? I do not use any products (cables, plugs) that aren't Apple and have had no power surges in my home. Could someone please give me advice
