When using the new function, you may recover a message for five seconds after deleting it. A confirmation dialog box stating “Message erased for me” will pop up following you remove a message. The dialogue box will also have a little “Undo” button. The text you just erased will resurface if you press the button. WhatsApp stated on December 14 that it would be experimenting with picture-in-picture functionality for iOS video calls. Since this capability has been available on Android smartphones for quite some time, Apple’s products fall even further behind. The iOS version of WhatsApp’s picture-in-picture functionality is presently only accessible to beta users; the functionality will not go out to the general public until next year.
