Sorry if this is a known Issue, I've tried to find a Bug Report related to Sync Issues and IPTC Metadata being overwritten but...
This issue started with the August release of Lightroom desktop 13.5
What I have found is that if you have a file that is synced to the Cloud and you change the IPTC Metadata in LR Desktop, when the file is re-sync with Creative Cloud. The metadata will be over written by the old Creative Cloud data.
i’m not sure if it’s every field that has been this issue but I do know for sure that:
Are definitely being over written.
(When sink is enabled on the collection; I will change one of those fields and 5-10 seconds later, The old metadata repopulates the field)
In addition to this issue sink is corrupting some of my Photoshop files.
in recent days, I have found a half a dozen files that have been corrupted by sink when I reopen them in Photoshop I get this error message.
“This file contains file info data which cannot be read and has been ignored”
I know the file was corrupted by sink because I created a new file, then sent it to Creative Cloud, and then reopened it in Photoshop and got the error message above.
Just as an FYI, I am on Intel Mac, and the OS, Lightroom, Photoshop or all up today. - CES
