-No need to exit your Facebook App before you visit your Instagram Account
Fusing all Facebook owned apps together is the work around for users not to exit the Facebook app, Messenger or Facebook Lite. Facebook doesn’t want you to leave Facebook, even if the applications you’re leaving Facebook for are owned by Facebook. The social network confirmed that users who also have Instagram accounts will now be able to navigate to those accounts directly via its main navigation menu, without having to exit the Facebook app to launch the Instagram app.
A Facebook spokesperson said of the A menu tweak was spoken of by a facebook representative, “We’re looking at ways to help people stay in touch with their friends on Facebook and Instagram. People on Facebook will be able to see how many of their friends are on Instagram.”
