How do I track my achievements, leaderboards and gaming progress with GameCenter being deleted in ios10?!!

Games that use GameCenter usually will have buttons within the app to access leaderboards and achievements. GameCenter wasn't removed, just the home screen icon to it. For now, it seems you can only access a game's leaderboards and achievements from within the app.

When I press on the thing in the app it says no Data available please help

I've been playing OLO since it came out. I've popped loads of achievements in this game and now can't see any achievements in game as it doesn't have a button.

Anyone know a way of loading them?

I would like to know as well! Please let know how to access Game Center in sims free play

Do u know how to check up achievements for sims FreePlay, cause I don't see a Game Center within the app
