Cannot complete verification on OptumRX home delivery signup for the AARP prescription discount card

My husband and I got our discount cards and found that the best pricing was with the OptumRx home delivery when we search drug pricing so we clicked the button to signup.  We were able to complete the AARP Verification form and the HealthSafe ID Let's Get Started form as well as the verification codes sent to email and text.  It's the Identification number (AARP member ID) that returns an unable to verify message on the HealthSafe ID pages.  I verified that my name, birthdate and AARP member ID on the HeatthSafe ID form matches my AARP account.  If I skip the verification, I get a different form that still will not accept my AARP member number as the identification number.  I have no access to order an OptumRX home delivery.  I received no help when I called the phone number for setting up home delivery either.  Do members have this benefit or not?
