A. 1. Ensure your casting device (like Chromecast) is set up correctly and connected to the same Wi-Fi network as your iPhone. 2. Restart both your iPhone and the casting device to refresh their connections.
B. 1. Check for updates for both the F1 TV app and your casting device. 2. If casting still fails, try using a different app to see if the issue is specific to F1 TV.
