Julie,
What is the date of your analytics-frame.html file? I have the latest version of Storyline 360 installed and the date of the analytics file is 10/29/2021 even when publishing a file today (11/12/2021). The analytics file in the published folder is the same date as where it originates from: C:\Program Files (x86)\Articulate\360\Storyline\player\{classic or unified depending on the player chosen}
If you have Storyline up to date but the analytics file is much older, that does seem odd. If not, I'm wondering if there's something else going on with your project.
