Ubuntu 20.04 Firefox 82.0 (64-bit) Network connection after entering the ID it says device added and shows it in the device list. Vizio with ChromeCast. Then when I try to cast the icon shows Video sending is not revealed. Then when icon turns blue and is clicked it says sending video but says it's sending to the site your watching it from. Not the Vizio. The user ID was found under system information UID: [Number]
