How do I view "New Posts" on mobile website?

When I go to the forums on my computer, I always have the option to see "New Posts" at the very top of the screen. But when I go to the mobile (Chrome on Android) website, I don't have that option, and I can't find it anywhere. Is there a way to see the "New Posts" from my phone?

It was missing, sorry about that. I've added the button to the account menu.
