This week something changed with the Youtube app on our Samsung smart tv. Now whenever we open the app the regular Youtube screen starts to come up showing recommendations, etc, then it quickly switches to a welcome screen asking us to sign in. The links on it are not responsive, we can't interact with the screen to try to log in or take the other actions it offers. But if we hit the select button it loads and starts to play a random video, and then we can exit that and look at our Youtube menu and see that we are logged in to our account.
Why is the welcome/log-on screen coming up when we are obviously already logged in? This is very annoying. I'm attaching a photo of the screen.
