Game streaming from console not working for me, even though FAQ states that the UK is supported

all you are doing is streaming the image from the console, the console has to be used the same way as you would on the tv, a controller is only supported, i don't even think the games that support KnM even work over streaming and still have to use a controller.

Cloud streaming wont be on the cards for me for a while. Our area doesnt support good or stable enough internet yet to even consider it. And as yet I think a lot of the UK is in the same position. I see many benefits for it though and suspect it is
the future.

SO basically because it's a content download, they reserve the right to prevent you using previously purchased content, even though the EU always has compatability with games since the region is the same? IE if you buy a Sims disc from Germany and a expansion
in UK, they work together - unlike if you bought one from USA and one from UK.

Point being my xbox is from the UK - the game was bought in the UK so my licence is valid and microsoft cannot legally prevent me playing the game just because I moved!

Yes, I am aware. And that's the problem I am trying to get help fixing. Rather than letting me stream the game it's showing me the manage button, even though it's not even possible to install it on my console. It should be showing me the option to stream it rather than manage it, but that's not the case.

Sorry to hear you did not receive the Ebon Flintlock for watching the Mixer stream. You will want to review the Xbox Mixpot FAQ page. As it states,
Mixpot rewards are limited and not guarenteed to all viewers.

Keep an eye out on the forums though. It sounds like the Moderators may be posting the rewards status soon.
