I want to add my mobile phone number on Netacad. However, I am experiencing issues with the mobile number toggle switch on the Cisco account security. The toggle switch cannot be moved. If I manage to switch the toggle, I will request the discount voucher. The discount voucher is available for 2 weeks. Please help me.
