Hi, did you happen to figure out anything here @Israa? I am facing the same problem for iOS beta. On trying to attest a newly generated key it's giving back an invalidKey for iOS 17 betas.

App Attestation always return same error on iPhone 8 with iOS 16.7.2, we did restart iPhone, reinstall app and it is still the same. We have customers who are also affected.
