Is it true that with Ajax loading, any Javascript you have on an individual page will not run at all?

I just ran into this problem with some JS embedded on an individual page not running. And when I say not running, I mean not being executed AT ALL when a user navigates to the page. Not just "not working". E.g.

   console.log("I'm running");

Having searched a bit I found some words on this page https://support.squarespace.com/hc/en-us/articles/115000253288-Ajax-loading that say:

Quote

"Occasionally, Ajax may conflict with embedded custom code"

Now, that's not quite the same as saying "none of your code will be run" at all 🙂

Anyone know the answer?

Maybe update the documentation if it is indeed the case, as my experiments seem to show.

All the best,

Please provide a working link to the site and point out the JS..
