I am a new Xfinity customer, I went with Xfinity because I understood I could use my existing Roku devices to stream TV. I have successfully authorized 2 Roku devices (Premier+ & Ultra models) unfortunately a 3rd device (Premier+ model) is giving the following error: Error createDrmSession.403-102. This error is presented whether the device is wired to the LAN or on wifi. I have noticed the device that is NOT allowing authorization is Premier+ Model #4630X while the Premier+ Model that is working is #4630RW - both have the same software version. Do you have any thoughts as to why one Premier+ would successfully connect while the other will not?
