Why do some people like to withdraw messages after sending them? The first case may be that they sent the wrong message, so they withdraw it. In the second case, it may be that he feels that he no longer wants to send it to you, so he withdraws it. Sending and withdrawing messages is not a preference, but a habit. If you send the wrong message or for any reason, you like to withdraw the message. But if you have seen it, it has nothing to do with withdrawing or not withdrawing.
