The fifth personality game, sending messages to friends, succeeded, but my friends couldn't receive my messages. Who knows why?

The rejection of the message means that you have been hacked. If you delete your WeChat, the system will pop up a message asking you to send verification, indicating that the message refuses to be blacked out.

Since the other party no longer has you as a friend, it is possible that the other party added you but deleted you, and you just processed the information added by the other party here, so you have him in your friend list, but you are not in his friend list.

In this case, communicate with him first and ask him to remove you from the blacklist, otherwise you can't send a message.

You can't change yourself, only the other person removes you from the blacklist.

If you delete your friend, let him agree with Friend Request.
