My t.v. forgets that I've chosen the soundbar (optically connected) as the audio output. Half the time, when I turn on the t.v., both the soundbar and the t.v. speakers are on, and I have to go into settings and change to soundbar. Annoying.
I've sat on a Twitter chat w/ a Samsung agent for over 2 hours, with LONG waits after I send a message. Terrible service.
