Apple TV 4 Issues after Software Update

Hello,

After a software update...which plonked TV App, ITV Hub and My5 on my Apple TV 4. I have been unable to connect to my itunes library.

I am also unable to connect/pair with any of the family devices via the apple tv remote app. It goes through the motions but it just doesn't appear on the app!!

I have done the whole series of off/on, delete reload, even home-sharing off and back on...and router off and on restarting my mac, our iphone/s, ipad and apple tv.

Help!!!!

Johnny.
