Same issue. Spent hours and hours to no avail. Only happens with TiVo 4K Stream with YouTube TV stations such as CNN and MSNBC. Excellent internet connection, as checked by visit from friendly Xfinity tech, everything just fine - except the 4K Stream w YYTV. Started happening a couple of weeks ago and is now unbearable. I really would like to resolve or will need to get another streaming device.Same problem and so annoyed. Mostly because I like the remote for the Stream since it turns my tv on and off, switches inputs, and controls volume of the sound bar.
