If on a mobile browser, I've found that you need to check the "Show as 
standard website" box to have the reply buttons show up. For some reason 
they don't on the mobile version of the page. This is on Chrome on an 
Android phone. If accessing from a "normal" computer, you should have the 
reply buttons there.
