Hi I've just purchased the Google Chromecast so I can watch the Presto streaming service and it works great! as it's compatible with Chromecast? but I'm having trouble installing the google cast extension on my phone and tablet so I can view the web via the google chrome web browser on my TV I successfully installed it on my laptop just by going to the pull down menu on the google chrome browser clicking on more tools and extensions then adding the extension to chrome? my laptop is running windows 10? But I cant do the same on my tablet and phone which are both android powered devices? I've gone to install the google cast receiver but its saying its saying 'my device isn't compatible with this version'? Do I need an updated android device in order to install the cast receiver? what's the deal?
