WhatsApp will remove View Once Message from the desktop due to privacy concerns.
For privacy reasons, Whatsapp is no longer offering it’s desktop users the option to view once-delivered messages. A new function called screenshot blocking was launched by WA last month, and it prevents users from taking screenshots of their conversations. This was implemented after the view once messages functionality so that users couldn’t capture screenshots of their conversations. Whatsapp is eliminating the “view once” option for PC users because the screenshot-blocking feature is only available on mobile. Since November 1, this modification has been implemented.
A view-once message is only visible to the recipient, therefore if you open WA on your desktop, you won’t be able to see it. This means that you can no longer use it on the web/desktop version of WhatsApp, WhatsApp for Windows, or the beta version of WhatsApp for macOS (native catalyst app). You also can’t use the desktop site to send a view-only message at once.
However much WA tries to protect its customers’ privacy, some users will always manage to capture a snapshot of their conversations. Even after receiving a message on another phone, some people may attempt to snap a photo of your location. You should always think about the recipient carefully before sending a message.
All at once, these capabilities are being taken away. At some point in the future, desktop computers will no longer be able to transmit or receive view-once messages. The user’s privacy is protected by this function, as otherwise sensitive and confidential data may fall into the wrong hands. People are happy with the upgrade since WhatsApp is constantly striving to provide a pleasant and secure messaging environment for all users. It’s annoying when a desktop site won’t load a message, but at least you can still read them on your phone. Therefore, it isn’t really an issue.
