Why is there no option to synchronize data in Huawei Watch app?

Started a single movement.

1. First, upgrade Huawei Health App to the latest version, and upgrade the watch/bracelet to the latest version.

2. Secondly, the motion linkage function needs to be operated when the mobile phone is connected with the watch/bracelet.

3. Finally, please ensure that the connection and pairing between the watch/bracelet and the mobile phone are normal, and refresh the synchronization data in Huawei Health App.
