thanks @yevgen 
Has there been any investigations done about auto-posted wordpress posts requiring a site purge for them to be seen?
As detailed here: New Wordpress Posts not showing on Homepage when using APO
Purging the index file does not work and I have to do a full site purge for them to be seen everyday
We purge cache automatically for existing entries using: Cloudflare-WordPress/cloudflare.loader.php at master · cloudflare/Cloudflare-WordPress · GitHub. Probably there is a hook we need to add for auto-posted wordpress posts. It’s not straight-forward which one we need based on plugin development - add_action hook for completely new post? - WordPress Development Stack Exchange. If you can verify the one hook we should use for your use case I would be happy to release a fix. Is it any of this: plugin development - add_action hook for completely new post? - WordPress Development Stack Exchange?
Thanks. I’ll have a look and get back to you
WP plugin 4.4.0 version includes the fix for cache purge on auto-post.
