Hmm, interesting. On my test site, when I sort by latest, it shows me the most recent products first, and older products are further down in the list.
Are you sure that the products shown further down your shop page are in fact the newer ones?
One thing you might try, on a staging site if possible, is a conflict test. The best way to do this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Test out the sorting again
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict.
You can find a more detailed explanation on how to do a conflict test here.
Let us know, thanks! ??
