What happens when I open WeChat to receive information?

It is because the notification of WeChat receiving new messages is closed.

Open wechat and receive a message. Notification permission is not turned on. Just open the notification permission of WeChat. The following are the specific steps:

1, enter WeChat settings, open the mobile phone WeChat APP, click Me in the lower right corner, and select Settings.

2. Open the new message notification, click the new message notification, and open the button on the right side of the new message notification.

3. Activate the notification authority, enter the WeChat notification authority setting interface, and activate the "Allow notification" option. Then you can receive a new message notification.
