To update a live view through Push Kit, you need to set the default data processing location to China. Otherwise, messages may fail to be delivered, affecting the function of updating a live view through Push Kit.
To set the data processing location under Project settings > Data processing location, perform the following steps:
Sign in to AppGallery Connect and click Development and services.
Click the project for which you want to set the data processing location.
Go to Project settings > Data processing location, and click Edit.
Select China in the Enable column, and set China as the default data processing location in the Set as default column.
Click Save.
If the data processing location is different from your server location, or is different from the location of a user that the app serves, messages will fail to be sent.
