Wow this is truly amazing. Whatsapp is currently trying in its beta version to recall messages and to even delete them from your notification tab.
If you've ever sent a WhatsApp reply to the wrong thread, sharing your pet-name for your partner with a business colleague, or you've engaged in a spot of drunk-messaging, it looks like you'll soon have the opportunity to recall the message either before or after it is read.
WABetaInfo, an unofficial Twitter channel devoted to news of WhatsApp betas, spotted the feature. WhatsApp is finally testing the Delete for Everyone feature: the server finally works, and it successfully recalls the message.
Also, if the server works this does not mean that the feature is currently enabled.
In a couple of subsequent tweets, it was noted that it also removed the message from notifications on both Android and iOS devices.
The last feature it tested, picture-in-picture for video calls, was spotted testing in late July and was made available to all Android 8.0 users earlier this month.
