Agree with the above. Your hubby need to add you to his card and then all 3 of you will appear. Then your partner can order a duplicate card for you to have. It's a simple process through the app.
We filled it with my details but I think I joined his card when we got married so when we got the new card with our baby’s name in the mail we both got a card each
Have you considered having a family card with all 3 of you on it?
