Can step by 800,000:
https://www.canterlot.com/discover/?&before=1707940130&latest=1707140130
https://www.canterlot.com/discover/?&before=1707140130&latest=1706340130 - shows older posts
https://www.canterlot.com/discover/?&before=1706340130&latest=1705540130 - shows even older posts

but the problem is that it also shows all of the newest posts for all of those links. "?&before=" -> "?before=" makes no difference.
