Currently the copy function allows for copying of all files/ containers even those with access restrictions. Even though, technically, there is nothing stopping users from downloading and re-uploading these files somewhere, we shouldn't provide a convenience function for people to achieve this.
I also don't know how to validate this - I cannot create a file with an AR on it, and I don't know any specific file that has an AR that I don't have access to.
Try this file: syn7851703
This should give a reason why the file was not copied.
, we validated.
