Recently I've noticed an issue with my iPad Air 2 where I plug it in for charging and everything looks ok however it's not charging. If I unplug and plug it in again it eventually starts charging. This started around the time iOS 11 came out however I can't say it's related. The charger works fine with my iPhone and a have a couple different chargers sitting around the house. Is my iPad Air 2 dying or is there a fix to this issue?
