We have a recurrent reported bug which is about that people cannot see the initial publication when they switch the remote staging on.
We should modify the https://help.liferay.com/hc/en-us/articles/360018172231-Enabling-Remote-Live-Staging page at least and all other sources where it's not obvious how it works.
On the page the "When Remote Live staging is enabled, all the necessary information is transferred over the network connecting the two servers." and the "You've officially begun the staging process!" sentences may be misleading as they can be understood so that there is an immediate, initial publication.
Could you please make how it actually works?
Let me know if you have questions.
