They will still work as standalone apps but will have the same underlying architecture.
This update will make use of the current Messenger button in the Facebook app, but you will now be taken to a new "Chats" section rather than opening a separate Messenger app. Researcher Jane Manchun Wong was the first one to spot the new feature under the testing phase.
As of now, the feature seems to be in its early stages, and Wong said that the "Chats" section will only have basic text, and won't feature reactions, video chat, calls, or photos tabs. "We do not have any additional details to share at this time". The development has come at a time when the tech giant is preparing to integrate its messaging service on all its owned social media platforms- Whatsapp, Instagram and Messenger.
This all tracks with recent news that Facebook CEO Mark Zuckerberg plans to roll Instagram, WhatsApp, and Messenger into a single platform.
For now it's unclear when this Chats feature will make its way to the main Facebook app - or if.
Mr Zuckerberg has not yet issued a statement to inform the sites and apps users, who run into hundreds of millions, why their systems are offline. It is not certain as of now as to when the new Messaging integration or interface might become available. "We're working on making more of our messaging products end-to-end encrypted and considering ways to make it easier to reach friends and family across networks".
You may remember that Facebook spurned off Messenger way back in 2011 where it was originally called Facebook Chat.
