Hi, I have an issue with the chromecast built-in, I cannot send video to TV from Chrome browser and from IOS device. When I try to send the video, there are no device found. Until a few months ago, it worked fine. The firmware is the latest.
Here's what worked for me:
(1) making sure that the Chromecast Receiver app is updated to the latest version via the Google Play Store
(2) if #1 was already done -> clearing data + cache of the Chromecast Receiver app
(3) restart the TV
BTW: this is assuming that the TV set and the mobile device are both connected to the same network and the TV is connected via WiFi.
