Recently, Facebook announced that it is bringing Messenger and Messenger Room’s screen sharing feature to mobile apps. Until now, the screen sharing feature was available when using video calling only is desktop offerings. However, now it will be available on Android, iOS and desktop versions of Messenger, Workplace Rooms, Messenger Rooms, or any other Facebook app that allows you to make a video call.
While users can share their screens with eight people in Messenger, they can share their device screen with up to 16 people in Messenger Rooms. The Messenger Rooms allows up to 50 users to get on a video call and began rolling out to all Facebook users since May.

Soon, new features will be added that will let Rooms creators limit who can share their screens. Additionally, Facebook also intends to expand the feature to support sharing with up to 50 people in Rooms. While the new feature is more of a consumer-focused, it is not much of help to professionals.
Though the Messenger app on Android and iOS have started receiving an update, it could be some time till all devices receive the update. This is because the rollout is staggered and occurs in waves.
