user_a0b7p4, Thanks for confirming this for us. Let's get this fixed. Did you get to step 5 from our previous message where the success message indicated that the activation was successful? Were you able to access live TV previously on the Apple TV device or is this the first time accessing LiveTV and getting this error message?

I have never been able to access the Xfinity Live TV from the Apple device since first installing the app in February. Again, it works on the TVs in the home with the FireStick.
Yes, I get the success message on the separate device (both phone and computer)

Same problem. Same device. Plays purchased movies fine. Will not show LIVE and will not play StreamPix movie started on another device. Shows "Application Error TVAPP-00400 We're sorry, something unexpected just happened. Please try again."
The Xfinity Stream app works on any Apple TV device that supports tvOS version 15 or later, including:
Apple TV 4K (2021)
Apple TV 4K (2017)
Apple TV HD (2015)
Have you attempted to force close and relaunch the Xfinity Stream App? This includes signing out and signing back in again. Also, remove and reinstall the Stream app.
