I think this is related to a bug with Apple's Zero Sign On. The workaround right now, if prompted for your TV provider during the reset/install process, select ‘Do not allow’.
If your Apple TV is already set up and you're having trouble with the Pik TV app, go to the Apple TV Home Screen, then navigate to Settings -> Users and Accounts -> Apple TV Accounts -> TV Provider -> Sign Out
Also, if anyone from Telus is even reading this.. I'm happy to help troubleshoot with someone who actually knows what they're doing.
I can pull logs from the AppleTV if you need, and am happy to be tossed into any kind of beta/testflight program you may have.
Maybe because it is an intermittent issue, and not happening to all? PikTV works fine on my Apple TV of a few years age.
