Bought new remote to replace old one. Trying to pair with same smart tv following the instructions -3 times and also unplug/replugged the roku stick. Nothing happens (the remote pairing light on remote starts to flash as soon as batteries are placed in it - so remote and batteries seem fine)?
Can you please clarify what you are trying to pair? Are you trying to pair your new remote to control your TV or are you trying to pair the remote to your Roku device? What Roku model device are you using?
