Sorry to hear about the problems you had... on my Cox cable box everything loaded and worked great with the app. Hopefully they get it sorted with Comcast.I watched the race today on demand using the Peacock app. The video quality was good enough. The app itself is not that great, infact is sucks. The app on the Comcast set top box launches and just spins. It has never worked when ever I try it. The app on the Apple TV refuses to take my comcast login. With Comcast service one gets the Peacock Premium access. Only the app on the iPad works ( allowed me to use the Comcast login). However the screen mirroring for the app is either blocked or just plain busted.
I got to watch the race so I’m happy. Since I switched from DirecTV to Comcast I lost the Olympic channel.
Let’s hope this works for more than just this weekend...
