I have had my roku ultra less than a week. After setting it up the remote unpairs itself after a few minutes. I am constantly having to remove the batteries and replace them in order to reconnect the remote. I tried using the button under the battery cover that does nothing. I have tried restarting the whole system without any luck. I have excellent wifi signal and have tried using my 5g option on the router. The only thing that works is to remove the batteries and replace after 5 seconds. This is very annoying! Please fix this issue!
