After Xiaomi's mobile phone upgraded the system, the recommended SMS was gone. How can I get it back?

Hello topic, the recommended SMS you mentioned should be the notification function in the mobile phone software. You updated the system of Xiaomi mobile phone, and the default notification function may be turned off. Just turn on the notification function in the phone settings-notification function. You may need to set up some separate notification functions in the software to make the notification function available. After the system is updated, individual spam messages may be blocked, which can be set if necessary-in messages, all messages can be set not to be filtered or blocked.
