Matching accounts

• Can I add a third-party to my account?
• I'm still not matched with my co-parent. What do I do?
• If I don't know my co-parent's phone number or email address, how do I match our accounts?
• My co-parent created another account. Can you match my account to their new account?
• What if my co-parent won't sign up?
• Why does it say my account is "Pending Match"?
