Published vs. non-published reports - what's the difference?

Your software
My Mautic version is:v3.0.2
My PHP version is: 7.2.33

Your problem
My problem is:
What does published vs. non-published reports refer to? There is no explanation that I can find and published usually means “public” in most uses of the word so does that mean published as in to the general public who can access reports with the right URL, or published to registered mautic account users only.

These errors are showing in the log:
My brain log is showing confusion.

Steps I have tried to fix the problem:
Take an aspirin. . .

From what I know, you can schedule a sending of reports to your email with some Cron job. Unpublish a report, and it won’t be sent. That’s one difference.
