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."

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
