Thanks for the inquiry.
Try 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. Once the channel has been added back, try authenticating the channel with your account credentials.
Does this clear up the issue you are seeing? Please keep us posted.
