When I try to use the management API from the iOS SDK to update the user’s metadata, [manageAPI patchUserWithIdentifier:identity.identifier userMetadata:[self fieldsToDictionary] callback:^(NSError \* \_Nullable error, NSDictionary \* \_Nullable data) It keeps giving me an HTTP error. Error: Failed with unknown error “errorCode”: Bearer, “message”: Bad HTTP authentication header format, “statusCode”: 400, “error”: Bad Request] Any ideas why I’m getting this error? ---

OK. I’m very confused on how to update metadata from Auth0 SDK for iOS. My user is logged in and authenticated. I don’t understand why I can’t call the manageAPI to patch the user. Is there something I’m missing? @prashant ---
