I'm trying to understand how to integrate Game Center into Playfab.
after reading the documentation, I don't understand why the API LoginWithGameCenter requires TitleId. but LinkGameCenterAccount requires GameCenterId?
compare to Facebook, both LoginWithFacebook & LinkFacebookAccount APIs require the same AccessToken.
also I can't find the example for Unity on how to use LinkGameCenterAccount. how can I get GameCenterId? I saw another topic to use Social.localUser.id
is this information correct?
Do I need to upload to App store(Testflight) to make it works, or only build from Xcode directly to device is enough?
