[Youtube in general] Sign in with Google Account fails

[effleurager]

The sign-in mechanism appears to be broken, making downloading using private lists impossible; attempted on private playlist and Watch Later using respective extractors. Changing Google Account settings to allow "Access for less secure apps" did not solve the issue.

Seems to have been a temporary Sign in issue on Google's part, not the application.
