We even used Google Chrome as the browser and still no way to do it. We went online and verified it will only do that from a PC not from a tablet. I don't know how I missed that but I did. It won't even work on an Android tablet. And this thing has been available for a while now so it's not like its too new. It seems like Google comes out with a great product and then just kind of drops it when its not interesting anymore (i.e. Sketchup). I know I've been guilty of that before. I hope they update this thing in the future but for now I'll just stick with Apple.
So I packed up the Chromecast and it's going back and Apple TV is in their future. I once again proved to myself why I prefer Apple products. They just work.
