Xbox 360 Game Recommendations feature is gone?

They have removed various things from the console, including apps, over the years for whatever reasons. If something is not worth maintaining I can understand the removal of it despite there being a few people that may be using it. It can be costly to
maintain things and if you have something new that you want to add, unfortunately that means another thing has to be cut.

It's possible that Microsoft removed it because hardly anyone used that feature. But if you want the feature back, then post in the ideas thread here

Have you tried power cycling the system, there is also a service alert for core features of xbox live so trying after the service alert is gone is recommended https://support.xbox.com/en-US/xbox-live-status

I want the option to mute the audio of a snapped ap/tv. If I'm playing a game and watching tv I want to have the option to mute/unmute the tv audio.

+1 for the above suggestion. I would like this to happen.

Although ONE is not launched where i am from but i was thinking it would do this though. Hope it will be updated in future.
