game centre app is missing

The only way that seems to let you use the Game Center is Settings » Game Center ; you can invite or play with players nearby over Wi-Fi or Bluetooth but I don't think that you still can check your points or the stuff you used to do . If the Game Center REALLY means to you , you could downgrade your iOS version

I'm having the same problem I case we can't see or add other people to our game center how can I look at my game center

There isn't a separate Game Centre app in iOS 10, you now log in/out of an account via Settings > Game Centre

Same here how can I find it or download it

There isn't anything to download, there is no Game Center app in iOS 10

I am having the same problem on my phone. It says I am logged in but does not offer me any options for games. Also, I have lost all the data that was saved on one of my games.

It is very silly 😟

The app has been removed, you can still log in and out of an account
