I'm watching the Telemundo feed. It's actually showing the race without any commentary.
I had the same problem. There is no box in chrome. YOu need to watch it on edge or firefox.
Just click on bottom right just below video box.
Yes very annoying. The weird thing is it's on the regular NBCSN app with commentating from Swangard - so you don't get Hutchings, tollefson like Chicago feed. Bets option is to to do both.
I'm getting no commentary on NBC SPORTS GOLD?
