I stopped getting emails from Yahoo re: responses to my comments on Yahoo News on Dec. 2. Help chat couldn't help and I phoned the help line twice. Once we turned on a notification button, second time we turned on a different notification button. I tested it while on the line. Nothing. She upped it to a "second level manager" but came back with Sorry, nothing we can do. Why would email notifications of responses to my comments have suddenly stopped and not be restartable?
