Whenever I attempt to start NetFlix it locks up and just freeze at various points of the process. It is intermittent where it locks up, but it does it every time. However, this only happens on one of my Xfinity devices. All other Xfinity devices do not experience this issue. I have restarted this device, powered it down by removing the power cord and event performed a complete refresh of my account using the Xfinity application, but the problem persists with this device.
