Every time I drag an audio file from Pro Tools browser window into session edit window, the clip fails to copy with "Unknown Error".
I am using Pro Tools 18.104.22.1687 on macOS 10.13.4. I have the setting enabled to copy audio files on import. If I close the session and open it again, the files are successfully copied. But this is very annoying to have to do every time I want to hear the audio file in the session.
