Why can't I add you when I receive the text message?

1, the micro signal was reported and degraded invisibly, so the friend adding function was blocked. You can open the WeChat service message box in WeChat, and reply to the question and wait for Tencent customer service to solve it.

2. If the profile of WeChat users contains sensitive characters or the information of friend verification application is illegal, it will be automatically blocked by the system. Please modify the configuration file or verify the content of the application message.

3, click on the phone address book, there should be that friend, then join the blacklist, quit to set the blacklist in privacy, add it again from here, and then restore the blacklist.
