The site does show the skp to main content for me using a screen reader. For those using MacOS, you have to change the keyboard navigation method with Option + F7 I think, or go to system settings > keyboard. Originally, Tab only moves to important parts of the window, because MacOS tries so hard to be clever for you. Honestly, I rarely use skip links, because they sometimes don't even work and just leave my screen reader on the skip link, so I just use headings and landmarks.
