I was able to successfully login to the YouTube Video (not the youtube leanback) till last evening from my WDTV Live SMP, since then I am getting “invalid username…” error.
I remember seeing this error a few months ago and had fixed it then by removing the google+ profile/account that Google automatically associated with my youtube login.
I saw that Google had again added the google+ profile to my youtube login, so I removed it again from the youtube login but that did not help. I am still getting the “invalid username…” error.
I even tried adding a bran new youtube login but google+ is added to it by default and even after removing google+ from the new youtube login I get the “invalid username…” error.
Has anyone else encountered this issue recently, and if so is there a solution to this?
