Actress sisters Kylie Jenner and Kim Kardashian criticized Instagram on Monday, calling on the app to stop imitating rival TikTok.

Jenner and Kardashian posted a message to their hundreds of millions of Instagram followers that said, “Make Instagram Instagram again.”

“Strop is trying to tiktok, I just want to see cute photos of my friends,” the post read.

Mark Zuckerberg CEO Metamis, which owns Facebook and Instagram, is pushing into short videos, a market dominated by TikTok on mobile.

Jenner and Kardashian are both very influential on social media. In 2018, Jenner slapped Instagram competitor Snapchat’s makeover, which led to a 7 percent of the parent company.

Shares of Meta were relatively low in after-hours trading.

Instagram did not immediately respond to CNBC’s request for comment.
