henryfbp "The Google API is insecure"
No, Googles attestation being insecure is not why GOS cannot pass said attestation, its because its not authenticated to do so.
GOS cannot pass Play Integrity API as GOS isn't authenticated to do so by Google. They would need to whitelist GOS or make an API that doesn't require approval from Google.
Its fully Googles choice and there is a good chance they will never allow GOS to pass the Play Integrity API
