Terrible on the go app. 30 second commercials to watch a 10 second clip. Livestreams play for 5 seconds then buffer for 10-15 repeatedly. I know it's not my service because I have full reception on 4G and every other media app works fine at the same time. I tried clearing the app cache and data to no avail. You're better off watching ESPN on a home TV app, which defeats the purpose of being a mobile app.
