Legacy contact not working

If the directions indicated in the support article How to add a Legacy Contact for your Apple ID - Apple Support do not work, try restarting your device. That can clear up odd issues. If you still have problems, contact Apple:

Refer to this document for ways to contact Apple --> Choose your country or region - Official Apple Support

Select your country (also look for "other" regions), then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:

Contact Apple for support and service by telephone --> Contact Apple for support and service - Apple Support

This undocumented step worked for me too...except when I got to the next screen, I got an error message saying 'Unable to Add Legacy Contact. Try again later.' I've been trying again later, and still the same error message. I mean, seriously? Apple?

Glad you got it to work. :-)

Such a simple step of tapping on the contact number... I couldn't figure it out! Thank you for sharing that tip.
