Hi George,
Whenever the “save_post” or the “wp_insert_post” or the “new_to_publish” actions are triggered, the plugin will automatically index the new product.
The screenshot only tells, that the cron job had nothing to index at that moment, but that does not mean the products are not indexed.
If any of the above filters are triggered upon the import, then the cron will always return 0 items indexed.
Do the stats show any items not indexed?
