@Sharshep-
Your account indicates you have a Streaming Stick 3600. This $#@% forum doesn't do a good job of keeping your listed device(s) up to date (my list is several years out of date) -- is that still what you are using? And what new remote did you purchase?
Streaming Sticks can only be controlled by Roku Voice Remotes because these remotes connect via WiFi signals that can penetrate behind the TV where Streaming Sticks are normally used. Remotes that connect via line-of-sight IR (infrared) cannot be used with Streaming Sticks, so Roku non-Voice remotes, Roku TV remotes, or universal remotes that control via IR cannot be used with Streaming Sticks.
