Does this also work on a Chromecast with Google TV?

Hi,

I was able to install appgyver preview app on my chromecast. I was also able to link it to my account. I also see my projects and start them.

But I only get a spinner and nothing else. Is this platform not supported yet or does this platform need anything specific in the project?

It was a simple demo which works fine in webview preview on my PC.
