Live TV and the Plex Web App NOT WORKING

I have just purchased a hdhomerun and set up the plex DVR functionality.
I can record programs and watch live TV on my IOS devices. However, there doesn’t seem to be an option to watch live tv from my browser. I can only see the record icon. Please help???
I have tried it from the plex media server and also from the plex web app (plex.tv site)

What server version are you running?

All good John. I needed to manually update server.

Cheers
