I know this is pretty late to the party, but it sounds like whatever USB you had the Chromecast plugged into was power cycling every hour and screwing the connection. You might wanna look into a way to turn that off in your TVs settings but honestly, there are better ways to stream Kayo to your TV.You calling me a liar??? ME???
Nah honestly I haven't tried it much but to be specific I have a Chromecast Ultra and every 10-15 minutes the Chromecast would freeze totally and I'd have to power cycle it. I don't use Chromecast for anything else and after 2 days of frustration I just went HDMI from my computer to the TV and play it that way. That was back in March/April, never tried again since.
They said they were going to have an Xbox app "Early 2019!" and I've emailed them about 5 times and get a generic response back. Once they make an Xbox app kimlo will be a happy camper.
