Instagram plans on bringing back the chronological feed in 2022.
They got rid of it in 2016 in favor of the controversial engagement-based ranking feed. Speaking to lawmakers at a Senate hearing, Adam Mosseri said the company has been working on "a version" of a chronological feed for months. Instagram also confirmed they'll also add a "favorites" feed, which will surface posts from designated friends higher in the feed. Both feeds will be optional. Mosseri has consistently defended its algorithmic feed despite persistent complaints from users, saying that a chronological feed made it "impossible for most people to see everything, let alone all the posts they cared about".
