I moved the hub closer to the entertainment center, and thought my problems were solved, but alas, no such luck. It did make an improvement but there's no way to get it any closer. It used to be further away and off center. Now it's centered and closer to the floor.

The weird thing is that the Smart Phone App works flawlessly with the hub, so it must be an issue with the interaction of the Elite remote itself with the new TV. No way to tell if it's a software or hardware issue, but I suspect the former.
