i have a different problem. When i set up my corporate mfe, it automatically asked me to come up with a security code. It asked for letters.and special characters. The mfe did not work, i deleted my corporate mfe account and it.still doesn't let me get rid of the security code, despite all the other accounts set as non-provisional. In order for me to get rid of the security code, i have to wipe out the phone clean. This is a big bug that needs to he addressed.
