Instagram dropped the chronological feed in favor of a crap (in my opinion) algorithm back in 2016, and after almost two years of complaints by users, they're working to make an improvement.
No, our beloved chronological feed isn't making a comeback. Instead, they're adding a "new posts" button.
It should be more coherent to browse the app now that you won’t lose your place because your feed randomly refreshes, and there shouldn’t be as many disparate time stamps to juggle. Instead, you’ll be able to manually push a “New Posts” button when you want to refresh the feed.
Instagram says, "Tap the button and you’ll be taken to new posts at the top of feed — don’t tap, and you’ll stay where you are."
I've updated the app on my phone and don't see a fancy new button yet. I'm curious to see if this will actually make a difference!
