I wasn't quite sure where to ask this so I thought I try posting in on these forums. Whenever I try and comment on a video on Youtube while signed in I get the window above popping up.
Also when I try and click on the Notifications icon it says "Please sign in to view your notifications" when I am already signed in! I click on "Sign in" and nothing happens. I have tried signing in and out again but the problem is persisting. I have only just started having this issue and I've never had it before. Does anyone know a way round this?
