the Info icon at the bottom of the app screen on the iPad has an exclamation mark next to it. If I select the icon I get a panel saying "Home Network Required The selected Virgin TV box has not been found on the current network. Make sure you are connected to the same network as your Virgin TV box, then try again." There are three buttons: Re-scan, OK and Need Help? If I press "Re-scan" it just takes me back to the previous screen where I selected the Info icon.Same for the "OK" button. Otherwise there is no error message.
I have tried removing and reinstalling the app on the iPad several times with no effect. What I haven't tried yet is a complete reboot of the V6 box. I put it on stand-by overnight. Waiting for a suitable time as it interrupts viewing for a long time. I will let you know if that makes any difference.
