In a bid to improve user-experience in its messenger app, Facebook-owned WhatsApp has brought several new features in the last few months, including delete for everyone option in the group to erase unintended messages in wrong channels, colored background in the status update and more. To be precise, one hour 8 minutes and 16 seconds, beyond which, the user can not erase messages.
The latest version of the WhatsApp beta app can be found in the Store here.
However, The Verge reports that WhatsApp has allegedly changed its delete feature. Now, if the upgraded algorithm receives a revoke request, it checks its database for a message with the same ID, and then checks if the current date is less than 24 hours when when the message was sent, and only then proceeds to delete the message - using the same ID that had been generated previously. Using this notification system, many users, thanks to modded and unauthorised WhatsApp for Android versions, were able to delete any message for everyone with messages dating back to 3 years.
WhatsApp has made a decision to stick to 24 hours as the reference time period here to ensure that there is ample time for the recipient or recipients in case of a group chat, to receive the revoke request.
What's more, if you do delete a message, the other people in the conversation see a "message deleted" alert - so they know that you've said something you've regretted, and may ask you some awkward questions about it.
According to a report by WABetaInfo, a fan site that tests new WhatsApp features early, in order to stop such bad users, the messaging platform has implemented the new feature. This ensures that nobody can tamper with the feature to delete messages for everyone.
