I recently added the Bluetooth channel to my lineup just to see what it was. Nothing I needed, so tried to delete it, but the remove channel option was not there. I checked to be sure I hadn't accidentally subscribed, but there was no subscription listed.
Now what?
Try going back to the Streaming Channels Search from Home Screen. Select the Bluetooth Audio again and you should be presented with "Remove Channel" option.
That worked - thanks, mucho!
