I have successfully authenticated with YouTube and I can successfully download private YouTube playlists.

However, when I then try to download my Watch Later playlist using:

youtube-dl https://www.youtube.com/playlist?list=WL

I am getting the above error saying this playlist does not exist.
It correctly recognises to use the youtube:watchlater info extractor.

I've tried username/password/2FA on the command line. .netrc credentials and interactively entering my 2FA token. In all 3 cases I could download other private playlists I have, but I'm getting the same error message for my watch later playlist.

In the log provided you did not specify any form of authentication.

@dstftw Updated log with .netrc authentication.

☝️ This is me downloading a private playlist of mine. For some reason, it gets 500 and asks me 2FA token twice every time, but it works.

When I use user/password/2fa on the command line it gets cookies and then I'm able to download without additional arguments.
