    Hello
    I was using mirroring with my note 3 and TV and it was working great. Until a few days ago. Now it won’t work. Very frustrating. I can’t imagine what could have happened but I would like to fix it. If it worked once, no reason why it can’t again. Thanks for your help and have a good evening.
