For a short period of time, Instagram โ€˜accidentallyโ€™ changed its layout for a short period of time.

According to the Facebook-owned platform, it was a bug which caused the design to be rolled out.

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 โ€œthis #instagramupdate almost ruined my morning!!โ€ while journalist Alex Heath of the online service Cheddar remarked that it โ€œseems maybe intended to reduce mindless vertical scrolling?โ€

Adam Mosseri, who heads Instagram for Facebook, tweeted that the new design was โ€œa test that went to a few orders of magnitude more people than intended.โ€

Sorry about that

Instagram said a short time later that it had rolled back the redesign to the normal vertical scroll.

โ€œDue to a bug, some users saw a change to the way their feed appears today,โ€ said an Instagram message posted on Twitter.

โ€œWe quickly fixed the issue and feed is back to normal. We apologize for any confusion.โ€

Some Instagram users remained upset over the glitch. โ€œNever do it again plsโ€: tweeted one enraged user.
