If you logged into Instagram on Thursday morning and noticed a drastic change, you were not alone. The platform rolled out a new look that sent the internet into a frenzy.

Many users opened the app to find that their feed scrolled from left to right instead of up and down like usual.

The company has since reverted to its old format, but not before droves took to social media to express their disapproval. Many said they hated the change.

While the redesign was only meant to be a small test, it mistakenly affected way more people than expected, according Adam Mosseri, head of Instagram.

“That was supposed to be a very small test that went broad by accident. Should be fixed now. If you're still seeing it simply restart the app. Happy holidays!” he said in a tweet.

A few admitted they had a hard time navigating the latest interface.

Others were so frustrated that they threatened to delete the app from their phones.

On the other hand, there were a couple of folks who actually liked the new design.

And some people were not affected or logged into Instagram after the old format returned.
