I am using Related Articles list component in Napili community. It is visible only for logged user. The component is not visible for not-logged-in user.
Edit: Also, the issue seems to be with Trending Articles, Trending articles shown to logged in user are different from what it is showing to Guest user.
Guest user has Read Access to all article types.

KNOWN ISSUE 2:
Related Articles List in a Community will not show for guest user if user language does not match site context language
