Refreshing the message menu
WhatsApp will make the send button more functional with the next update. A new menu will be displayed when the submit button is pressed. Users will be able to quickly send their once-viewable message, choosing from a photo or video. However, GIFs will not be able to be sent in view once mode. At least in beta, WhatsApp doesn’t allow it.
The new message menu, which will allow users to send photos and videos that disappear after being viewed quickly, is under development and will be available in a future version of the application.
