I know how important it is to do extensive research before making the decision to change your services to the Ignite TV platform.
I tested out the channel list on my end using the link that you provided. It did request my address information but once accepted I was able to scroll down a bit then select Channels and the channel list appears with a search option. If you are having issues at the address verification screen it could be a browser-related issue. A quick way to verify this is to try another browser, if that is not an option please clear the cookies and internet data cache from the browser you are using.
You can also use Incognito Mode in Google Chrome or Private Browsing in FireFox/Internet Explorer/Edge to see if the same issue is persistent.
