After the photos that disappear after viewing, WhatsApp is now working on applying this temporality to text messages, so that they can be read only. That is, they disappear once the addressee has seen them. The new type of temporary or ephemeral message has already been seen in the beta version for Android (version 2.22.25.20), where it is accompanied by a new send button with a padlock.
This new button present in the message composer is that it indicates to the user that they can send a text of a single reading, and that it will disappear from the conversation when the recipient has opened and read it.
Ask the sender to send it again
If the recipient tries to see it again, a small symbol with the number 1 and a notice that the text has expired will appear in its place, but you can ask the sender to send it again, as collected by the specialized WABEtainfo portal.
This type of temporary message is preceded by an informative page, which indicates that given the private nature with which it has been designed, it is not possible to take a screenshot, copy it, share it with other users or save it.
This is, for the moment, a feature in development that is expected to arrive in a future update of WhatsApp for Android, first for users of the beta version.
