Hi Graham it’s a LAN connection to the router and yes it is showing a IP address have noticed the netflix app is missing from the screen you see at the first press of the home button
I had the same problem last night and could not watch any YouTube so had to use my AppleTV instead.
Not only is the players screen blank and privacy settings as others have said, but the YouTube icon has gone from the list of players visible at the bottom of the screen when you press the FreeviewPlay button.
I have done plug pull, reset etc and still no joy.
