ESPN app gives error "this channel is not part of your TV package"

Try this.

Delete the app. Unplug your modem. Connect your device to a mobile hotspot. Once connected, download the app. Once downloaded log into your cable provider, if it’s still logged in from previous time, log out and log in again. This should actually allow you log into your cable provider manually instead doing to automatically. Once you’ve successfully logged into your cable provider, plug your modem back in and it should be working now.
