Why can't WeChat plus friends receive the verification message?

The other party of this platform cannot receive the verification message for the following reasons:

1, the micro signal was reported and degraded invisibly, so the friend adding function was blocked.

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. There were too many people in Friend Request that day, and more than 320 people could not receive the information. Solution: After 24 hours, the system can resume normal use after re-obtaining the data.
