Reason for Change

The change is made to eliminate invalid data sync across devices.

Change Impact

This change is a non-compatible change.

Before the change:

When data is added, deleted, or modified in a KV store with autoSync set to true, data will be automatically synced to the devices in the same network.

After the change:

When data is added, deleted, or modified in a KV store with autoSync set to true, data will be automatically synced to the devices in multi-device collaboration in the same network.

Start API Level

Change Since

Adaptation Guide

The cross-device automatic sync of KV stores applies only to multi-device collaboration. For details, see Cross-Device Sync of KV Stores. In other cases, set autoSync to false. Even if autoSync is set to true, the automatic data sync does not take effect.
