Snap Inc.鈥檚 flagship platform has lost some luster, at least according to one social-media influencer in the Kardashian-Jenner clan.

Shares of the Snapchat parent company sank 6.1 percent on Thursday, wiping out $1.3 billion in market value, on the heels of a tweet on Wednesday from Kylie Jenner, who said she doesn鈥檛 open the app anymore. Whether it鈥檚 the demands of her newfound motherhood, or the recent app redesign, the testament drew similar replies from her 24.5 million followers. Wall Street analysts too have begun to notice, citing recent user engagement trends noticed since the platform鈥檚 redesign.

Jenner鈥檚 tweet was followed late Thursday by one from Maybelline New York, asking its followers if it should stay on the Snapchat platform. The beauty-product brand owned by Paris-based L鈥橭real SA said its 鈥淪napchat views have dropped dramatically,鈥 but it still wanted to connect with its followers.

Citigroup analyst Mark May downgraded the stock to sell from neutral earlier this week after seeing a 鈥渟ignificant jump鈥 in negative reviews of the app鈥檚 redesign. He expects the reviews could cause user engagement to fall, hurting financial results.

Meanwhile, as the app takes criticism, Chief Executive Evan Spiegel may become one of the highest paid executives in the U.S. After the company鈥檚 IPO last March, Spiegel got a $636.6 million stock grant that will be payable through 2020.

“Still love you tho snap,” Jenner hedged in a later tweet. 鈥斅Bloomberg
