2) Force close Covet Fashion
Log out of Facebook in your iOS device settings
Log back into your Facebook account via your Facebook App or www.facebook.com via the mobile web browser
Then relaunch Covet Fashion

The above steps should allow you to log into Covet Fashion using your linked Facebook account. Sorry for the inconvenience!
