According to the head of Instagram Adam Mosseri, the company was attempting to test the feature with a small percentage of users, but the bug caused a much broader rollout. The update looked similar to how Instagram stories appear, making users tap to see the next post.
Instagram mentions began trending on Twitter nearly immediately after the update appeared, with countless users up in arms about the change.
But everyone can relax. It remains to be seen whether Instagram will try to roll out this now-controversial feature again, considering the hostile feedback the test received.
A test change to Instagram got out of control. "We apologize for any confusion" an Instagram spokesperson tells TechCrunch.
While users have been shocked by this update, the horizontal feed has been in the works for some time, with Instagram originally rolling it out to a select number of users in October.

Although the change is as simple as scrolling left and right instead of up and down, it entirely changes the way in which users are accustomed to looking at posts on their newsfeed.
"The Instagram update is so trash it's worse than the Snapchat update", @samfloresxo tweeted. If you are still seeing the new interface, simply close and restart your app and the old layout should be back.
Instagram has apologised after a "bug" update changed some users' feeds, resulting in major backlash, which the social media platform said is now "fixed".
Minutes after the update went through on many phones, some noted that their app reverted back to infinite scroll and the update appeared to have been removed. Stop this chaos and bring back the chronological news feed. Scrolling up and down is a thing of the past, leaving most of us frustrated on why they made the change.
