U-verse address book additions not working

As someone who has had Uverse TV for13 years, I feel confident in saying that Uverse TV does not have any kind of address book.

Hi, thanks for replying! I'm a charter uverse subscriber (2005!), and yes, if you have uverse phone service, there's an address book feature. The best thing about it is that when somebody in the address book calls, their name shows up on the tv screen, even if they have unlisted numbers it is (was) great! But now I can't add new contacts.

Why are you asking your question on an AT&T forum?

umm, what?

I guess because it is the low-stress option? Customer service was useless - not unlike these oddly quick, denying non-responses, I was switched from tech to tech until I got lost in the tree. At least this is weirdly amusing.

It's a shame when technology services take these backward steps. A real shame.

What do you mean by "charter" uverse subscriber? I have VOIP, now called AT&T phone service, previously called Uverse phone service.

WHERE are you seeing an address book that you can add names to? Is it when you log into your account.

Edit: I see this option on the online portal. I have CID on my phone so I've only used the options on the phone service to block numbers.
