PDF highlights do not sync to Mac

While the share sheet was broken in DTTG I was using the built-in PDF highlighting for research. My PDF highlights will not sync from DTTG to DT on my Mac anymore. I am using a local WebDAV server that is solid, DTTG 3.7.6 on iOS 17.0.2 and DT 3.9.3 on Ventura. Anyone else having this problem? I tried making changes to the copy on my iPad after updating the iOS version and syncing again, no love. Files do sync back and forth between the Mac and iPad, but none of the highlights I made on the iPad will sync to the Mac.

Anyone else experiencing this?

Are others changes (e.g. renamed or added items) synced back to the Mac?
