Instagram said on Thursday it accidentally rolled out a design change to a large number of users and quickly ended the test after complaints from users of the Facebook-owned social network.
The redesign required users to swipe horizontally instead of the normal vertical scroll to see their feed, befuddling many members of the photo- and video-sharing application, which has over one billion users worldwide.
The move ignited complaints on Twitter where the hashtag #InstagramUpdate became a top trending issue.
Twitter user Jeffree Star lamented “this #instagramupdate almost ruined my morning!!” while journalist Alex Heath of the online service Cheddar remarked that it “seems maybe intended to reduce mindless vertical scrolling?”
