Re: Spectrum TV channel app won't open on Roku Streaming Stick or Streaming Stick+
Uninstall the Spectrum app. Turn off the security on your wireless router so that it's an open network. Reboot your Roku and connect to the internet. Reinstall the Spectrum app. Start the app and verify it now works. Turn your WiFi security back on. Reboot your Roku and connect to the network again. Start the Spectrum app. It should work now. Sounds unnecessary since other apps are still connected and streaming but this seems to work.
