B) Troubleshooting:

If your device is not syncing to the application, you can try the following:

First, ensure that your device's operating system and the Asia Miles by Cathay app are both up to date.
Next, ensure that the Fitbit account that is connected to the application is the account that is recording your activity.

Manually trigger the Asia Miles by Cathay app to check for new Fitbit activity by:

Click on the "watch" icon on top right corner of the Dashboard.

Click on your " Connected" device to check the Last synced time.

Click on the "sync" icon to collect the latest data.
