I am not famaliar with a "more options" button, but I do agree, it doesn't work because it is being discontinued. Google+ or bloglovin are the popular ones, there are other readers out there . I suggest building your follow list on one of those sites rather than trying to finagle GFC to work. Even if you get it working occasionally, it is just something that is not going to be around long run. I would also encourage bloggers who still have the follow link on their sidebars, to update it to a link for a site where users CAN easily follow.
I get frustrated with changes sometimes because I am habitual, but lots of people work hard to make their options for blog following intuitive, so give it a shot, and let us know what you end up using.
