Why did Optus remove the ability to cast the football to watch on the television? As a 70 year old my husband doesn’t want to be reduced to a watching on a small screen, our son installed Chromecast and it worked great so why is this option no longer available? Give us back this ability PLEASE!!
Chromecast is still available, I am present watching the Liverpool v man utd match.
My first guess is your Chromecast and your device are on different WiFi networks. Check that both devices are on the same wifi.
I have a similar problem with my Chromecast, sometimes it hangs and doesn't appear as an available option. I would turn it off from the source (wait a couple of minutes) and turn it back on.
Best of luck and have a great Xmas and New Year!
