issue now is in this part it returns false

ECPublicKeyParameters signingKey = KeyParser.ParsePublicKeyDer(signedKey.KeyValue);
            return VerifySignature(signingKey, signedString, signature);

in method VerifyMessageECv2 in class SignatureVerification.cs

@olufemitomilola004
When I set the IsTest parametr to true, VerifyMessage simply returns false exactly as this issue descibe. When I set IsTest to false, I'm getting No valid signing keys found in payload.

Then kindly confirm with Google to know if your payload is still valid because they do expire after 5days I guess. Also be certain that you are inputting the right gatewayId
