The new feature will enable users to retrieve a deleted message through revoke option.
WhatsApp is testing a new feature — Block revoke request —to prevent the misuse of its recently launched 'Delete for everyone' option allowing a user to delete sent messages.
The new feature will enable users to retrieve a deleted message through revoke option. WhatsApp will sent a new message containing the same ID as that of the deleted message which the user may want to revoke, according to WABetaInfo, a fan site that tests new WhatsApp features.
Earlier, when a recipient received this particular message containing the revoke request, WhatsApp checked if the ID of the message was present in the database and if the original message was found, it directly deleted it without checking any other important information.
Now, the application would check the current date and the date of the saved message. The message will be deleted if it is less than the new 'Delete for everyone' limit.
"A new WhatsApp for iOS update (2.18.31) is available on Apple AppStore. It is a bug fixes update but it has the new 'Delete for everyone' limit, that is one hour, eight minutes and 16 seconds," read the information on the website on Tuesday.
The algorithm would allow users to revoke deleted messages successfully, if the message was deleted in the past 24 hours. The reference time of 24 hours was decided after taking into account that the recipient's phone may be turned off at that moment.The deleted messages, however, may not be recovered after 24 hours as the revoke request will be considered invalid.
