A) How Apple Health automatic activity tracking works

You can sync an assortment of activity trackers and other health or wellbeing apps to the Apple Health app.
When there is new activity in the Apple Health app, the Asia Miles by Cathay app automatically retrieves and tracks your progress against your wellness journey daily goals.

Note
When the Asia Miles by Cathay app is open, the latest activity from the Apple Health app will be retrieved. Additionally, you may sync the latest activity record from the Apple Health app by pull down to refresh Wellness Journey homepage. If the application is closed for a prolonged period of time, it is possible that the automated syncing process may stop. If you log out of the Asia Miles by Cathay app, your activity from Apple Health will not sync. You can see the last time Cathay checked for new activity in any of your connected apps and devices by:

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

Click on your "Connected" device.

View the recently synced activity.
