Streaming unavailable

I don't understand how the streaming app on the fire stick is so archaic, and unavailable on Android TV. If you're a current customer this should be available, and to mirror. And Internet speeds shouldn't be sold for more than infrastructure can provide. It's literally like selling a Ferrari, and then telling a customer later it will only reach its potential on an unavailable track for life, but it would reach that speed if it could. We just can't show you.
