"This device (Roku Express 4K+) can only access Xfinity Stream on your in-home Xfinity Wi-Fi. Use the app on your smartphone, tablet or laptop to watch on the go, any time you like. (Error: TVAPP-00101) Isn't the whole point of this app so you can take YOUR Xfinity with you? The device is new and Xfinity has no fix except call Roku. "Roku Agent-assisted support is not available for your issue and/or model." Neither one will take responsibility for their INFERIOR product, SHAME ON BOTH OF YOU!
