Doesn't sync ever, this app sucks it's useless it never syncs it doesn't control anything the ONE time I managed to get it to work it had a REALLLLY bad lag with the sound. It was like watching a dubbed film only it wasn't actually dubbed!! Customer service was trash when I emailed them. I have a sound bar, the remote lasted 3 months was hardly used. Worst Vizio experience ever. I have tried reinstalling and setting up the soundbar again. To no avail. This is all trash.
