We are on our 2nd roku remote. The new voice remote's pairing LED immediately flashes once tbe batteries are inserted and doesn't stop. The pairing message also never appears on the TV. What's going on?
Restarting your Roku device, and your wireless router/modem is a great first step. Replacing the batteries in your remote can help. Changing the wireless broadcast channel on your wireless router, to one that isn't in use by another nearby wireless network, can reduce wireless interference and be extremely effective in improving remote functionality.
