I have a roku stick 3600x and it randomly stops responding to the remote most often when it is in an app, any app. Sometimes it starts working again after repeated button pushing, other times I have to power cycle the stick and then sometimes also repair the remote. Sometimes I can use the app on a tablet to pair again without rebooting it. But pressing the paring button on the remote alone doesn't seem to get the sticks attention. I am using the remote only about 5-6' from the tv and fresh batteries doesn't seem to matter ether.
