Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
Indexing on SERPs may take a while sometimes. Instant Indexing API basically submits your URLs to Google to let them inform that your URLs need to be crawled on a priority basis.
But the decision to index them is still solely decided by Google and it completely depends on Google when your URLs going to be indexed.
Hence we’d request you to wait for a while to see if Google indexes those URLs. If not, please share the affected URLs with us here, so that we can take a look as well.
Looking forward to helping you.
I am using instant indexing plugin. I have noticed that my post doesn’t show up in Google automatically. But when I do bulk submission, it will show. Why?
Hello,
Please note that the Instant Indexing feature submits the URLs to Google so they can be crawled faster and potentially indexed but still, it solely depends on Google if they want to index a URL or not.
However, we’ve checked the URL you’ve shared with the site:
operator and we can see that it is already indexed on Google:

Regarding the Action Scheduler notice, it is not related to your Instant Indexing. The notice is not an error, but a message stating that there are pending Action Scheduler actions that were not completed. However, you can add the following filter on your website to remove the warning:
add_filter( 'action_scheduler_pastdue_actions_check_pre', '__return_false' );
Here’s how you can add filter/hook to your WordPress site:

Thank you.
