It's a convenient feature to add right now, since most of us are stuck at home and can't watch movies and TV shows with friends like we normally would.
Up to seven people can watch at once, and each user has the ability to pause, play, rewind or fast forward for the whole group, keeping everyone in sync.
It's easy to use Disney+ GroupWatch, you just need to start the session on a phone or the Disney+ website.
Note: you only need to start the group on a phone or through the website.
