I am using Roku Sound Bar. I played a movie on the Roku Channel. When the first commercial break played, at the end of the 4th commercial the movie started over at the beginning. I could not fast forward because it was still showing Ad 4 of 4 in the upper left corner like it was still in the commercial segment. I clicked back to go to the movie title screen and then I clicked play again. It played another 4 commercial segment then started the movie where it should have after the first commercial segment.
