From my Chrome Browser, it does not show up in the list of available devices. Only for YouTube from laptop Chrome, it worked.
From my Phone (Samsung GS7), even YouTube did not work.
I have tried to get this work on multiple devices and it never worked . But then I found this app . You map . Tried on kitkat and lolipop android tv boxs and it works great . Will require a restart of two . Also doesn't require any special install any apk installer should work
Post back if it works
