For at least a week or two, perhaps longer, "Single Page - Sequential" display mode displays only the first category in my list of categories (in my case, World), with no tabs etc to show stories from any other category.
Opening the settings, clicking the Categories tab, and switching it to "Tabs (default)" then back to "Single Page - Sequential" fixes it... until I reload the page, at which point it's broken again.
I expected it to work properly lol.
