I have a new Samsung the Frame 55 TV model QA55LSO355W. The voice control on the remote was working fine but then stopped. I did a full reset of the TV, re paired the remote to the TV, turned the power off at the wall for 10 minutes then restarted. I had it set up with Google but since failing tried it with Bixby and Alexa with no success. The Blue, Red, Yellow, Green indication dots appear bottom left of screen when I push the voice button. All other functions on the remote work fine. Any advice or assistance appreciated.
