We just purchased a Samsung Class 8000 series TV - in part because my wife wanted to cast content from her iPhone 11. That worked seamlessly, but I'm having a hard time getting my Pixel 4 to do the same. We don't have Chromecast or any other streaming device. Is that a requirement? Or is there an app I need to download? There is no "SmartView" icon on my home screen dropdown menu, and if I go to "Cast" under Settings -> Connection preferences with the TV on, I get the message "No nearby devices were found".
