Instagram Accidentally Made Users’ Feeds Scroll Horizontally

It appears that quite a few users had a timeline that moved left to right, where posts could be tapped through as they can be in stories. When the new timeline appeared, Instagram surfaced a notice that said, "Introducing a New Way to Move Through Posts," and told users to tap through to see their posts. However, it seems that this may have been another short test rather than a permanent change to Instagram's feed. Rumors about such a move circulated in October, though at the time it looked like the feature would be limited to the Explore tab. — Scott Neumyer (@ScottNeumyer) December 27, 2018 A number of us at Engadget had the new feed orientation as well, though for some people, the new feature didn't reach all of their accounts. It seems this update was another quick test that Instagram has already concluded. We've reached out to Instagram for more information and we'll update this post when we know more. Update, 12/27/18, 11:08 AM ET: This story's headline and copy have been updated to reflect that this may be another short-term test instead of a permanent change. Update, 12/27/18, 11:20 AM ET: Adam Mosseri, head of Instagram, tweeted today that the sideways scroll feature was supposed to just be a small-scale test, but the company accidentally extended it to more users than it intended to. If you still have the sideways scroll and you want to revert back to the normal view, just restart the app.
