Some users completely lost their minds when Instagram briefly changed its layout from scrolling up and down to side-to-side.
Some even threatened to stage a boycott, others said "No. Instagram. No."
But don't worry. Everything is back to normal with Instagram offering an explanation, saying it was just a test.
"Sorry about that, this was supposed to be a very small test but we went broader than we anticipated," tweeted Adam Mosseri, head of Instagram.

The Menlo Park-based company also tweeted an update on Thursday, saying the change was "due to a bug."
Due to a bug, some users saw a change to the way their feed appears today. We quickly fixed the issue and feed is back to normal. We apologize for any confusion.— Instagram (@instagram) December 27, 2018
Here's a look at some of the reactions after the update was rolled out:
Only in 2018 could a company as large as Instagram release a new update and then receive such a backlash over it that they change it back 20 minutes later. Beautiful. #instagramupdate— Michael (@michaelbrown_10) December 27, 2018
