QQ and Peace Elite have synchronized news, why didn't they receive it?

This may be due to the following reasons: 1' s synchronous message function. QQ and Peace Elite need to be opened in the application. If it is not open, you cannot receive synchronization messages. 2. Maybe your account is logged into other devices, which makes it impossible to synchronize messages. It is recommended to check whether your account is logged in on other devices. If so, please log off other devices and try again. 3. Your network may be unstable, resulting in mail synchronization failure. It is recommended to switch networks or check network connections. 4. It may be that the synchronous message function between QQ and Peace Elite has failed, so it is recommended to wait for the developer to fix it. If the above methods can't solve the problem, please contact QQ and the customer service of Peace Elite for help.
