Automatically write to XMP does not write anything
Lightroom Classic 14.3.1; Windows 11; NEF photos from Nikon Z6ii
I have the box in Catalog settings "Automatically write changes into XMP" checked. I have confirmed this by checking and double-checking. I have also turned it off, shut down LrC, and then re-opened LrC and checked the box. The .xmp files are not updated "automatically". None of this helped.
Whatever changes I make to the .NEF files, the .xmp files are not updated. How do I know? At the same time I am editing in LrC or adding metadata in LrC, I have a Windows Explorer window on my screen showing the folder with the .xmp file in question. I make changes in LrC, the modified date on the .xmp file does not change, and the size of the .xmp file does not change. If I add a keyword to the file, such as "Barn", I can search the .xmp file with a text editor, and that keyword is not in the .xmp file. Even if I wait 5 minutes and shut down LrC and come back later, the size and modified date of the .xmp file has not changed.
If I use the command Metadata->Save Metadata to File, and observe the size of the .xmp file and the modified date of the .xmp file, these change within 2-3 seconds as expected.
I have reset the preference file, this did not help.
What should I try next?
