onMessageStatus callback (Android) returns FAILURE_DURING_TRANSFER

Hi

Im making my first Watch app where I send a text from my Android phone to my Fenix 5x when pressing a button at the phone app.

Im sending using the method below

public void SendToGarmin(String message) {

    try {
        mConnectIQ.sendMessage(mDevice, mMyApp, message, new ConnectIQ.IQSendMessageListener() {

            @Override
            public void onMessageStatus(IQDevice device, IQApp app, ConnectIQ.IQMessageStatus status) {
                Toast.makeText(MainActivity.this, status.name(), Toast.LENGTH_SHORT).show();
            }

        });
    } catch (InvalidStateException e) {
        Toast.makeText(this, "ConnectIQ is not in a valid state", Toast.LENGTH_SHORT).show();
    } catch (ServiceUnavailableException e) {
        Toast.makeText(this, "ConnectIQ service is unavailable.   Is Garmin Connect Mobile installed and running?", Toast.LENGTH_LONG).show();
    }
}

IQDevice in onMessageStatus(IQDevice device, IQApp app, ConnectIQ.IQMessageStatus status) is an unknown device and status is FAILURE_DURING_TRANSFER

Nothing appears on the watch.

Is there any link (key) between the apps on the watch/phone or will the watch app consume messages from any phone app sending messages?
