How to read deleted messages on WhatsApp
WhatsApp's deleted message recovery mechanism is based on the chat backup feature, which is built into the application and works by default. The function of deleting sent messages appeared in the application more than a year ago, but has time limitations: you can delete your message only within an hour after sending. But now it turned out that the disappeared messages can be restored, albeit with limitations.
So, to read the message deleted from the chat, you need to remove WhatsApp from the device, and then install it again. In this case, the entire chat will be restored from the backup in its original form - along with messages that disappeared before. However, this method only works if the device has not rebooted and if the archive has not yet been updated. By default, this happens automatically every night.
