Hi, App Attestation API "attestKey(:clientDataHash:completionHandler" returns "DCErrorInvalidKey 3" for some of the users. We have checked for first reason regarding if generated key is already been attested, we are generating new key and challenge every time. Could you please provide more details regarding more details for second reason "The App Attest service rejects the key."
