Why can't I log in to Leon?
The most common causes of login problems in Leon are an incorrect username, an expired temporary password, or an inactive user account. Verify that you are using the username assigned by your operator (not necessarily your email address), and if the problem persists, ask your Leon administrator to check whether your account is active. If the mobile app hangs on the loading screen, force-close and reopen the app or reinstall it before contacting Support.
