Barb - obviously you've never used the NBC Sports app on an AppleTV. First, you can't just subscribe to use it if you are a cable cutter. You need to use your neighbor's cable info to log in.
Then the app stutters and shows endless commercials, ruining the experience. And the bugs bugs bugs. NBC has included "shortcuts" to moments within coverage, but they always land in the wrong place and rewind and FF don't work most times. I attempted to watch on two nights and finally gave up. Check Reddit and some of the other forums to see how widespread these issues are. The app has only 1.5 stars out of 5 on the Apple store.
What a disaster in this day and age - why can't they give the Olympics to Netflix or someone else who at least has the bandwidth and can let you directly subscribe.
