Can you please provide us with more information regarding when you are seeing this message? Does this happen when setting up the device, when watching a channel, or does it just show up from the homescreen? Were you able to use the remote prior to this message?
With more information about your issue, we will be able to assist you further.
I could use my remote previously, but I cannot use it to confirm my choice.
Do you experience this issue when you are trying to access any other channel or is it just from Netflix? If Netflix is the only channel that you are experiencing this issue with, we would recommend removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more to see if it resolves the issue.
I still have this problem. Checked batteries. Turned off the roku prem box and WiFi. You can see the roku pages behind the message (faintly) but you can't get to them. Press OK as requested and nothing happens.
