I get this error message in the OS Logs when I run the sample code from this Apple link - https://developer.apple.com/documentation/sirikit/media/managing_audio_with_sirikit: Failed to fetch user token error: An unknown error occurred Return code is 0 too which seems strange as well. I've generated a JWT using swift run generateToken <team-id> <key-id> from the SwiftJWTExample package: JSON Web Token: "<token here>" Header: {"typ":"JWT","alg":"ES256","kid":"..."} Payload: {"iss":"...","iat":...,"exp":...} Signature: ... And have checked my team id and key id. I've enabled App groups for the extension and the main target, and Siri for the main target, and am running on an iOS 14 device, compiled with Xcode beta. Hope you can help me out!
