Facebook Messenger is releasing a bundle of products this morning — most notably, including cross-app group chats. Last year, the company introduced cross-app messaging between Messenger and Instagram, but now, users will be able to start group chats among Instagram and Messenger contacts.

Other additions today include polls in Instagram DMs, building off of the poll feature that exists in Messenger. Messenger is also adding a group typing feature to group DMs — regardless of which app you’re chatting on — to help users see when their friends are typing at the same time. Plus, as Instagram embraces video content, users will now be able to use Messenger’s existing Watch Together feature to view Instagram posts like Reels and IGTV videos at the same time.
