Camera Raw edit settings not saved to NAS

When making edits in Camera Raw (currently v16.4) edits are only saved in XMP if I save the files (as JPEG or PSD) from ACR. If I open the files in PS, or click Done in ACR, none of the edits are written to the XMP data, including masks, star or color ratings. This has been an issue for many versions of MacOS and ACR. If I work on the files from a local drive, all data is saved and available.

Currently running MacOS 12 and MacOS 14
