I get the following error when trying do download the watch later list:

I call it using my credentials, everything worked fine until about a week ago.

When I deliberately give a wrong password I get another error message (ExtractorError: Please use your account password and a two-factor code instead of an application-specific password.), so I think the credentials are OK.

Oh, and when I dump the page content, I see that yt-download actually gets a page with content like Sign in now to see your channels and recommendations! and The playlist does not exist..
Downloading other (public) lists works, though.

Argh! After several days of struggling with this, I find the simple solution. Within minutes after opening the ticket, of course. :-(
I got "A privacy reminder from Google". So I logged out of YT, and back in. After clicking away the info message, yt-download worked just like always.
Sorry for bothering you!
