My institution's Canvas Catalog environment has some custom CSS and JS at the main/root catalog level. We're still using jQuery but not using anything deprecated, thus it is compatible with 3.7.1. This morning, we're noticing the script is not executing, and the issue is sporadic. Sometimes it loads normally upon a hard refresh in the browser, other times not at all. No error message are displayed in the browser or console.

We have not made any changes to the customizations, but multiple users are encountering this intermittent strange behavior.

Anyone else experiencing anything like this?

I'm already looking at switching to vanilla JavaScript for our customizations, but can confirm things work as they are - when the script actually executes, that is.
