"sooo does anyone else not open Snapchat anymore? Or is it just me... ugh this is so sad," Jenner tweeted.
She later followed up with "still love you tho snap ... my first love," but the damage may already have been done.
Snap Inc.'s shares fell by over six per cent in Thursday's trading, a loss of about USD 1.3 billion in market capitalisation.
Jenner has huge followings on various social media platforms, including Twitter and Instagram.
