The function appeared silently to many users both iOS and Android: currently active for sending pdf
Latest news: on WhatsApp now possible to send documents. The company has not given official news, but a series of users, both iOS and Android, have seen the function appear among the sharing options. For now it seems to be limited to sending pdfs, but it is probably only a first step (if it is not a pdf, I will probably notify you of an error). To make room, on Android the "Photo" and "Video" options will be found under "Camera".
The pdf will be previewed, complete with the number of pages and file size – and documents can also be fished from Google Drive, Dropbox, eiCloud Drive.
The new function to be framed in the context of the news that seems to push the application towards the business environment: having the company also invested in encryption, messages will also be able to count on greater security.
