Hi, I have implemented Sign in with Apple on Android four months ago, and it work perfectly. We are using React Native with expo, using expo-auth-session and firebase function to get code back to start the token validation process. However, recently we start to receive invalid_grant with no error description while token validation, however the same client secret works on firestore without issue, which confuses us. According to https://developer.apple.com/documentation/technotes/tn3107-resolving-sign-in-with-apple-response-errors, the common reasons that I receive invalid_grant are: The client_id does not match the client for which the code was issued. The code has expired or has been previously consumed by the validation server. Is there any way I could differentiate whether is client_secret wrong or the code was used or any other reasons?
