I am trying to implement a YouTube upload feature on my website, I would like to accomplish this using Google's <google-youtube-upload> webcomponent.
But when I try to sign in using only a YouTube channel - which also is available as a login option - it says Object {type: "tokenFailed", idpId: "google", error: "USER_LOGGED_OUT"} in chrome's console.
It is working just fine if I log in using a Google+ account that has a YouTube channel of the same name associated to it.
Is it not possible to authorize using only a YouTube channel? Or am I simply missing something?
Thanks in advance.
