I can see why you say "the online chat is gone". They added couple more things to the Help & Resources list so the live chat is pushed all the way to the bottom of the list. With certain screen sizes and screen resolutions, you won't be able to scroll down to the bottom of the list so live chat is not visible to you. But it's there. I can't see the live chat button on my laptop. But i don't have this problem when using my phone or when I'm using my desktop. So I guess changing your screen to a higher resolution may help you with this issue.
