You must use your username to log in to the Stylist App. (The VO will allow you to log in using either your username or Stylist ID number, but the Stylist App will only allow login with your username.) If you do not know your username, you can find it in your VO under Settings > Username. The password is the same for both (note: all fields are case sensitive).
Please wait approximately 90 minutes from the time you joined before you try to log in to the app.
If you have changed your username or password recently, please wait approximately 90 minutes and try logging in again.
