Well, that rules out microsoft's family saftey settings as being the problem or the browser cache or  the device. And it sounds like you have played around enough in google+ settings. I give up. Go have a look at http://www.wikihow.com/Turn-Off-YouTube-Restricted-Mode and https://support.google.com/youtube/answer/174084 and follow them step by step just to see if it will work. If that doesn't do it, I think you are going to have to try contacting youtube support. https://productforums.google.com/forum/#!forum/youtube
