Only there is no page 3 of pop. https://poal.co/all/pop/3 Also the bottom of page 2 of Pop only has an arrow to go back to page 1. Another thing that's a bit odd: page 1 of pop does not have an arrow to go to page 2 at the top of the page. Instead, the arrow to page 2 is only at the bottom. This is on mobile. Edit: or maybe whether there is a page 3 of pop just depends if enough posts meet the criteria? Either way there shouldn't be navigation to an empty page. Edit 2: another interesting feature is you can just keep scrolling through empty pages of pop indefinitely using these navigation buttons. https://poal.co/all/pop/15 Edit 3: but on pop pages other than /all there doesn't seem to be the same feature that allows you to navigate to an empty list.
