Facebook 旗下有不同的社交媒体 Apps 包括 Facebook, WhatsApp 和 Instagram，但它们各自运作并不相连亦不能互相沟通。之前 Facebook 公司曾经透露会整合三者，让它们的通讯服务可以互相连系。
今天 Facebook 就公布会为 Instagram 上带来改进的 Messenger 体验。原先在 Instagram 画面 DM 图示会转换成 Messenger 图案，点按后会提示询问是否想体验全新的 Instagram Message 功能，用家可以选择更新 Update 或稍后才更新。但长远计，Instagram 最终也是会全面强制更新 Message，所以用家迟早也要更新转用。
更新后，用家就可以跨 Apps 沟通，在 Instagram 发 Message 跟 Facebook Messenger 沟通。除了基本 Message 发送，还有其他新功能包括 Watch Together, Selfie Stickers, Message Controls 等。
Communicate Across Apps: Seamlessly connect with friends and family across Instagram and Messenger by using either app to send messages and join video calls.
Watch Together: Enjoy watching videos on Facebook Watch, IGTV, Reels (coming soon!), TV shows, movies, and more with friends and family during a video call.
Vanish Mode: Choose a mode where seen messages disappear after they’re seen or when you close the chat.
Selfie Stickers: Create a series of boomerang stickers with your selfie to use in conversation.
Chat Colors: Personalize your chats with fun color gradients.
Custom Emoji Reactions: Create a shortcut of your favorite emojis to react quickly to messages from friends.
Forwarding: Easily share great content with up to five friends or groups.
Replies: Respond directly to a specific message in your chat and keep the conversation flowing.
Animated Message Effects: Add visual flair to your message with animated send effects.
Message Controls: Decide who can message you directly, and who can’t message you at all.
Enhanced Reporting and Blocking Updates: Now you can report full conversations in addition to single messages on Instagram, and receive proactive blocking suggestions across Instagram and Messenger when you add your accounts in the new Accounts Center.
Instagram 和 Messenger 新功能将会在小部份国家率先推出，但好快就会向全球推送。
