I was asked to change the file's Owner, I did it via Dataloader app, the issue is that it still showing the old user as Owner.
But the actual owner of the file is correct.
I even deleted the sharing to the old user, which is actually a ContentDocumentLink.
Also did a query to count those documents links where the
SELECT COUNT(Id) FROM ContentDocumentLink where LinkedEntityId = '<old user id>' and ShareType != 'I'
And it decreases everytime I remove the old user from the file sharing.
What can I do?
