WhatsApp, Facebook Messenger and other messaging apps allow users to delete messages after they have been sent. But what about WeChat? WeChat is a messaging app owned by Chinese tech giant Tencent. It has over 1 billion active users and is the most popular messaging app in China. WeChat allows users to delete messages after they have been sent, but it does not allow users to delete messages before they are sent. This means that if you want to delete a message before you send it, you have to either copy the message and then delete it, or wait until the message has been sent and then delete it. This feature can be useful for avoiding embarrassing situations. For example, if you are going to meet someone for coffee and you know that you will be talking about work in detail, you can send a message saying that you will call them later instead. If the person replies asking why you are not coming over, you can simply reply with a deleted message explaining that you will call them later. However, this feature can also be used for more nefarious purposes. For example, if someone sends a threatening or harassing message to another person, the recipient may want to delete the message before it is sent so that the other person does not receive notification of the threat or harassment. ..
