Kylie Jenner is one of the biggest influencers on Snapchat.

But now she says it "is so sad" that nobody opens the app anymore.

Snapchat may have just lost a very influential user.

Kylie Jenner, a member of the Kardashian/Jenner family, tweeted on Wednesday to her 24.5 million followers: "Sooo does anyone else not open Snapchat anymore? Or is it just me... ugh this is so sad."

In a follow-up tweet, she said: "Still love you tho snap ... my first love."

Perhaps Evan Spiegel, the CEO of Snapchat's parent company, Snap, wants to make a call.

Jenner, among the most important people on social media, is one of the first so-called influencers. She has more than 104 million followers on Instagram.

She has used Snapchat in the past to show off a new haircut and give her millions of followers a peek into her family life with her boyfriend, Travis Scott. She's a power user who posts frequently — and if she's seeing less engagement on the platform, that's a bad sign for Snap.

She's also been connected to the company professionally. Last year, she partnered with Snap to broadcast exclusive video on Snapchat in a show called "Ask Kylie."

Snapchat has historically had problems with retaining influencers who have felt more supported by other platforms like Instagram that have special programs for people with lots of followers and provide more data about their posts and followers.

Redesign problems

Jenner's change of heart may be related to a recent and controversial redesign of the Snapchat app.

A petition calling for Snap to bring back the older design garnered 1.2 million signatures, though Snap later said the new format wasn't going anywhere.

Jenner is apparently not a fan of the redesign either.

"Mm just saw the new Snapchat.. I don't know how i feel about it! What do you guys think?" she tweeted earlier this month.

Jenner's followers may not be using Snapchat as much, but the company said earlier this month that the number of people who opened the app daily had increased by 5% in the last quarter of 2017.

But it's still not a good sign for Snap when a massive celebrity says they feel as if nobody is using its app.

Jenner's not getting rid of her account, though. If you'd like to follow her on Snapchat, her username is Kylizzlemynizzl.
