CloudFlare preview → subdomain out of sync

My Pages site has been having issues all day. The preview site works fine, but the subdomain is older or broken.

Preview: https://75d45474.cs110-web.pages.dev/resources/

Subdomain: https://fall2022.byucs110.org/resources/

Notice the link to the practice midterm is missing on the subdomain page.

This page works on the preview:

https://75d45474.cs110-web.pages.dev/resources/practice-midterm/

but has a bunch of missing images on the subdomain:

https://75d45474.cs110-web.pages.dev/resources/practice-midterm/

This all works fine for me with the subdomain. Did you fix it, or is the problem ongoing but intermittent?
