That is not the issue.
If you using an older version of Apple News on iOS 9.3.5.
The “For You” section of the older Apple News App for, older iPads running iOS 9.3.5, is not showing updated content, BUT, if you go to the Favorites option, the contents in your Favorites should be up to date.
The “For You” section, for some unknown reason, is no longer updating/showing recent content.
Using the Favorites category, ALL Favorites content are giving updated content and any new content you add is still being updated, as well.
If this is unacceptable for you, think about switching to another third party news app, like Flipboard.
