You must have at least one console registered in a Insider preview ring as at this time Streaming is only available to Insiders for the purpose of testing functionality.

Trust me when I tell you that my xbox has plenty of bandwidth for 4k streaming. Netflix will not stream 4k in the app unless the movie is actually marked for 4K. The app only displays HD as the option, not 4K like it does on any other device that I have
that supports 4k streaming. I do notice the difference when streaming Breaking Bad (which is a 4k serious on Netflix) on my xbox one via Netflix vs streaming it from the Netflix app on my smart 4k tv. The 4k TV smart app shows the correct 4k option on the
show and the picture quality is wayyy better then on the xbox Netflix app.

Directly by the console. I'm streaming my console to the Xbox App.

Yes, I am in the Insider program.

You saved my life of gamer, thnk you so much 👍👍👍

I
downloaded the Insider app on my Xbox, but I didn't get the console streaming option in Xbox's settings. So I deleted all consoles registered in the Insider app, I deleted the app, downloaded it again, but now I have no consoles registered in Insider app,
still no option for console streaming in Xbox settings.

So I completely reset my console, but nothing changed.

And the Console Streaming app preview on my phone doesn't display the config screen like it did before. Now I have this (picture).

WHAT CAN I DO PLEASE, everyone is playing around me with this, I was waiting it for like 6 months, and now I just can't use it...

What ring are you on. Streaming was just launched globe so might be having a glitch check the insider hub
