A new feature has been introduced in the WhatsApp beta update 23.23.1.77 for iOS, enabling users to link an email address to their account to receive a 6-digit code. This information was previously shared on Net Workshop.
WhatsApp is adding a new way for users to access their accounts when they encounter temporary issues receiving the 6-digit SMS code.
WhatsApp was recently updated on the App Store, introducing version 23.24.70 for iOS. The official changelog for this update is lacking in details about the new features, with most of the information being outdated.
The bug causing slowness in the application for some users has been fixed, but its exact nature remains unknown according to the official changelog.
