Her post - combined with investors' fears over the redesign - reportedly resulted in the company's stock plunging 6 per cent throughout Thursday, taking $1.3 billion from its market value.
Jenner's tweet came after the social media company faced so much criticism over a new feature that altered the user interface on Snapchat.
"Sooo doe anyone else not open Snapchat anymore?"
While she didn't single handedly ruin Snapchat, she later tweeted: "Still love you tho snap... my first love".
"There is a general level of annoyance among users and many have made a decision to use a VPN app, or are using other risky apps or steps, to go back to the old Snapchat as that's how annoying this new update has become", he continued. Since its rollout began at the start of the year, Snap has found itself defending the redesign, most recently on Wednesday when it responded to a Change.org petition with the title "Remove the new Snapchat Update". But like the rest of the Kardashian clan, Jenner is a businesswoman who has used the app with tremendous success to help sell her line of beauty products. "With roughly 25 million followers, (Jenner) carries a loud mouthpiece that speaks to today's knee-jerk reaction in shares".
Kylie Jenner, who has been with Snapchat since the early days, described the current state of the social network as "so sad".
Many users have a complaint about the application's latest update, Kylie's tweet about not using Snapchat anymore worked as the testimony for the platform's sinking popularity. In addition, he stands by the major changes that the app re-design introduced: "Snap is doing the right strategic moves but needs to manage this process well".
"We hear you, and appreciate that you took the time to let us know how you feel".
Snapchat also said the update will make it easier for users to "further customize your own experience on the app".
Jenner's tweet went instantly viral on Twitter, racking up 315,000 likes, 60,000 re-tweets and 4,200 comments in 24 hours. It's entirely possible she says she doesn't like opening the app because she's seeing that fewer people are seeing her posts.
