TokenAuthenticator authorizedWith(...) function not calling completionHandler in iOS 26.x

[4428078amana]

I've aded WebexSDK through Pods. and i have a Service App (G2G) enabled. When i try to authenticate on real iPhone device running iOS 26.1 using this code for authentication:

`let authenticator = TokenAuthenticator(isFedRAMPEnvironment: false)
self.authenticator = authenticator

    let webex = Webex(authenticator: authenticator)
    self.webex = webex

    print("1️⃣ Calling webex.initialize...")

    webex.initialize { [weak self] isAuthorized in
        guard let self else { return }

        print("2️⃣ initialize completed. isAuthorized = \(isAuthorized)")

        if isAuthorized {
            print("⚡ Already authorized (cached)")
            self.isInitialized = true
            return
        }

        print("3️⃣ Calling authorizedWith(accessToken)...")

        authenticator.authorizedWith(accessToken: accessToken, expiryInSeconds: 3600) { result in
            print("4️⃣ authorizedWith callback fired:", result.rawValue)
            
            switch result {
            case .success:
                print("🎉 Successfully authorized!")
                self.isInitialized = true
                
            case .invalidToken:
                self.lastError = "Invalid Webex token"
                
            case .networkError:
                self.lastError = "Network error during Webex auth"
                
            case .internalError:
                self.lastError = "Internal error during Webex auth"
                
            default:
                self.lastError = "Auth failed: \(result.rawValue)"
            }
        }
    }`

The complition handler section never get called.

@4428078amana just to confirm, is the https://github.com/webex/webex-ios-sdk-example working for you? I was able to successfully log in with a Service App Guest access token there using the authorizedWith(accessToken: method. Can you please confirm?
