Well, I think a “Revision” is not what we need.
A user submits a form and by that creates a post with status “Draft” with the user being the author. We have a 2nd software, which communicates with our WP installation, which publishs that post via API.
Now we want to notify the user, if this post gets updated (once again through API).
So there is no “revision” which happens.
I tried other plugins, which are focussed on pure notification things (Better WordPress Notifications and Notification) and have to option to notifcy on post_update. Both have issues with the caching plugin (WP Rocket) that we are using in terms of sending out the same notifications multiple times.
PublishPress is doing a good job for us, it´s just the “update_post” thingy, which we are missing.
