You may or MAY NOT see an answer box. On my cellphone with Google Chrome browser, I DO see an answer box. On my desktop PC, I did Not see an answer box. When I try to post my answer. I ger a "Privacy violation" in red. Sometimes I get "Question is in wrong state" in light gray. That means usually means there is a problem with .y answer or my phone has a problem or there is another technical problem, like the phone has lost the wifi connection or something has timed out.
On their answers, you MAY see a Comment hyperlink on Google Chrome, but when you try to post your comment, you get "We are having problems. Please try again later."
What you see depends in the device AND the browser you are using and whether the browser is in desktop MODE or not. On Google Chrome, desktop VIEW is a very different thing.
