Not sure why Instagram got rid of their chronological feed in the first place... but they've heard your complaints! In a blog post Instagram shared on Thursday, the company said we hear you. Insta isn't going back to a solely chronological feed. They are "making changes to ensure that newer posts are more likely to appear first."
Instagram is also testing a "New Posts" button that lets you choose when you want to refresh the feed. There isn't an exact time frame for when this new algorithm will roll out, but the company said more changes will be coming. More information about that will be shared down the road.
