I am looking into getting Xfinity TV and Internet at my house but the package does not include On Demand. My parents currently have Comcast Xfinity with On Demand that I use online. Does anyone one if I were to sign into the Xbox Xfinity App at my house (after getting Xfinity internet connected) will the app work using their log in? I have seen conflicting reports and figure someone on here will have the answer. Thanks in advance!
