My iPad was working perfectly using TV Anywhere but I have lost the control of my TiVo box (top right hand side)
This would suggest that your TiVo is not connected to your home network or your iPad is not connected to your home network.
How is your TiVo connected to your Superhub?
Is your iPad connected to your Superhub?
The iPad is on my Home network wirelessly and when I check the TiVo box it says it can't now connect, it was fine for a long time but now it won't connect. The TiVo connection to the Superhub is via a TP-Link powerline.
Thanks for your post and apologies to hear you're having an issue getting things working again.
