Just a thought.
They already made Lite versions of Facebook and Instagram.
And a lot of the new functions (stories, screen share, and the avatar emojis) only come as bloat for users like me.
So i think they should make an official app that came without those “features”, having a priority on simplicity and data saving.
Many use the messager to stay in contact with people even if they don’t use facebook itself much, especially on phones so it absolutely did if you ask me!
