I just paid for my stage 1, I got sent a receipt that contains a reference number, and a link to a form. I clicked the link to the form (tech nation), and I was told I had to update my eligibility before proceeding. I clicked the button, and got presented a form. In the form I am being asked for the reference number I got, and a UAN but I did not get the UAN in the email and I can’t proceed without it. Or am I missing something?
