Thanks for your post and a big welcome to the Community. I'm really sorry to hear that you are having an issue with accessing TV Go on your device.
This can sometimes happen if you've rana software update on your device or changed your settings. We can refresh things for you to regain access though.
In order to do that I will need to pass data protection with you so I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
