CTRL-BAR was working for me for some time and recently stopped by displaying "ERROR" when button is pressed. It appears to be connected to the phone, the app and the car. The LED's turn on and off with the button and the SPLIT function only changes it on the CTRL-BAR screen but not the car. All other functions result in ERROR. I deleted and reinstalled the app, removed and readded permissions for TESLA, etc and still ERROR.
