In the August 2019 update post, it says that modern pages can now have vertical sections. I don't see the option to add a vertical section or any documentation on it. Has anyone figured it out? If it has to be a home site, the wording of the post should be adjusted.
It's coming and it's part of the so called Home Sites...however I believe that this vertical sections could only be available at site homes pagers...by the way, we can only wait until Home Sites are released
