Thanks for your post and welcome to the Community. It's great to have you here
Apologies for the issues you have had trying to view the channels in the TV Guide. Currently there is a known fault which we've raised up under reference: F004038362
We are working to fix this asap for our customers but in the meantime, you can use the online version of TV Anywhere as the listings remain unaffected.
Once we have any updates, we'll be in touch to let you know.
