XFINITY APP ON XBOX ONE

I talked to Xfinity, they said they had the app already on 360 platform and it's up to Microsoft to utilize the app on the one console.

Unfortunately, Xfinity is mistaken here.

Microsoft only provides a marketplace to distribute apps from third parties like Xfinity. As Microsoft doesn't own publishing rights for Xfinity, only Xfinity can make a Xfinity app for the Xbox One.

While there are means to get Xbox 360 games working on the Xbox One through Backwards Compatibility, it wouldn't make sense for the Xfinity App. And even then, Xfinity would have to give Microsoft the rights to "convert" the app to Backwards Compatibility.

I'd assume the Xfinity support agent didn't know what you really wanted, or was too lazy to actually help you.

I agree, We should have the NHL app, as well as a Comcast/Xfinity App on Xbox One. Access to on-demand content from XFinity would be great!

Hope this helps mate

It doesn't appear that there is an app specifically for Xbox One for Xfinity Streaming. Alternatively, you could download apps for particular networks you'd like to watch (USA, SyFy, etc) and sign into those using your Xfinity credentials. Hope this helps!

There is no date or information available on XFINITY for Xbox one, However, I would definitely call them up and express your desire to see the app on Xbox one. 1-800-XFINITY - Comcast i'm sure also has forums you may want to join in order to voice your interest
in this app.
