Facebook updated the experience of sharing 360-degree photos with other users. Specifically, users can now change the initial view on their 360 photos on iOS, Android and Chrome on desktop.
With this update, when a user uploads a 360 photo on mobile, they can now drag their finger to set the initial view for the photo. This will be the view that other users will see before they access the full 360 photo. On desktop, users can click the edit button and move the mouse to set the initial view.
