Invalid OAuth access token - Cannot parse access token'

[zhong-meta]

Hello,

In response to the upcoming changes to ATT enforcement, we made changes to the iOS SDK and the SDK no longer provides valid user access tokens in scenarios where the user opts out of ATT. The access token validation or Graph API requests may throw errors like OAuthException - “Invalid OAuth access token - Cannot parse access token”. Our recommendation is that users integrate Limited Login following the official documentation: https://developers.facebook.com/docs/facebook-login/limited-login/ios
https://developers.facebook.com/docs/facebook-login/limited-login/unity/

See more details here.

Hi @zhong-meta
It's still a marvel for me why an optional advertising identifier influences the validity of the login access token. It defies all rules of software engineering. Can you provide any details why does it have to be this way?

使用limited login接口之后，报错190，Bad signature。
从facebook拿到AuthenticationToken，然后调用Firebase.Auth.FacebookAuthProvider.GetCredential(AuthenticationToken)，再调用firebase的SignInWithCredentialAsync来登录，就会报错。
请问使用limited login后，该如何正确处理SignInWithCredentialAsync调用呢？

@owllyi 請問你解決這個問題了嗎？

[owllyi]

iOS Nonce登陆一次就失效了，需要再次拉起登陆来signin
link一次，signin一次。拉起两次

[owllyi]

string nonce = FaceBookManager.GetRawNonce();
credential = Firebase.Auth.OAuthProvider.GetCredential("facebook.com", accessToken, nonce, null);
m_Auth.CurrentUser.LinkWithCredentialAsync(credential)

17.0.0这个版本在iOS17上如果拒绝了idfa就会登录失败，要用服务器JWT格式校验token的方案，客户端要升级Facebook SDK版本和Xcode到最新版本；
