YouTube; unable to sign in under Safari...

[The_Prodigy1982]

Guys,
I need your help here...

I'm unable to sign in into my YouTube account, using Safari.
However I AM able to sign in through Firefox.

- Safari constantly shows me the "Sign in using email or phone" screen, when I click 'next' the same screen pops up again.
I already tried deleting YouTube cookies through the Safari/Preferences/Privacy/Manage Website Data.. but that doesn't help.

Anyone else having this problem??

Maybe disable any Adblock software you have running with Safari.
