Hope this helps mate

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 guess Xfinity/Comcast wanted all there subscribers to just use there XFINITY app, I tryed the xfinity app and it stinks. I took it out. Thats what everyone should do, to protest. Do not download or use xfinity app. I will stick with CRACKLE, It has married
with children....lol

If the Xfinity app does not show in the app marketplace (like it did for me), search for it "Xfinity"

Was that Xfinity that they were using? I didn't even take notice to that. That's what I have, the Xfinity platinum package. That's awesome!
